“It was just regular growing up, of course, the kind everyone does - but it still hurt him, I know, like the memory I have of the time he dropped me off at the train station when I was going back to Chicago. I could see him through the window of the train, but he couldn't see me through the tinted glass. I waved, trying to get his attention as he walked up and down the platform trying to figure out where I was sitting. From up in the train, he looked so small. If he'd seen me, he would have smiled and waved, but he didn't know I could see him, and the sadness on his face was exposed to me then. He looked lost. He stood there on the platform a long time, even after my train started pulling away, still trying to catch a glimpse of me waving back.”

“My father told his acquaintances about that for years, even though both Hannah and I had given up on wormholes and the Child Genius series very soon afterward. That must have made my father sad, as it had made him sad when we stopped being excited about family vacations, when we stopped being open about our interests, and left home and pursued lives of our own. It was just regular growing up, of course, the kind everyone does, but it still made him sad, I know, like the memory I have of the time he dropped me off at the train station when I was going back to Chicago. I could see him through the window of the train, but he couldn't see me through the tinted glass. From up in the train, he looked so small. If he'd seen me, he would have smiled and waved, but he didn't know I could see him, and the sadness on his face was exposed to me then. He looked lost. He stood there on the platform a long time, even after my train started pulling away, still trying to catch a glimpse of me waving back.”

“Sometimes when we were hiding behind the breakers with the crowd, he'd hold me so tight, I'd think he's not just holding me, he's holding onto me, like I'm stopping him from falling off. I'd see him looking at me and his eyes were so full of...I dunno. Like he was about to cry. And, it's stupid, I know, but I think maybe he's hurting because he loves me and I don't love him, and this great lump used to come up into my throat and I'd hold him tight and try and squeeze him as tight as I could and try as hard as I could to fall in love with him the way he loved me.And then other times I'd think, it's just the way his face is that makes him look like that.”

“No one has really seen me in years.” Blake looked at the sky. “Sometimes I wonder how they know I don’t have a home. I try to dress decently.” He waved a hand at his jeans and army jacket. “I think it just seeps out of me. I’m not the same as everyone else.” He shook his head, pulling himself out of his despair, and looked at Livia again. “But when you saw me for the first time, you actually saw me. You saw me, and then you smiled like I was just the same as everyone else on that platform.”

“ON THE A TRAINThere were no seats to be had on the A train last night, but I had a good grip on the pole at the end of one of the seats and I was reading the beauty column of the Journal-American, which the man next to me was holding up in front of him. All of a sudden I felt a tap on my arm, and I looked down and there was a man beginning to stand up from the seat where he was sitting. "Would you like to sit down?" he said. Well, I said the first thing that came into my head, I was so surprised and pleased to be offered a seat in the subway. "Oh, thank you very much," I said, "but I am getting out at the next station." He sat back and that was that, but I felt all set up and I thought what a nice man he must be and I wondered what his wife was like and I thought how lucky she was to have such a polite husband, and then all of a sudden I realized that I wasn't getting out at the next station at all but the one after that, and I felt perfectly terrible. I decided to get out at the next station anyway, but then I thought, If I get out at the next station and wait around for the next train I'll miss my bus and they only go every hour and that will be silly. So I decided to brazen it out as best I could, and when the train was slowing up at the next station I stared at the man until I caught his eye and then I said, "I just remembered this isn't my station after all." Then I thought he would think I was asking him to stand up and give me his seat, so I said, "But I still don't want to sit down, because I'm getting off at the next station." I showed him by my expression that I thought it was all rather funny, and he smiled, more or less, and nodded, and lifted his hat and put it back on his head again and looked away. He was one of those small, rather glum or sad men who always look off into the distance after they have finished what they are saying, when they speak. I felt quite proud of my strong-mindedness at not getting off the train and missing my bus simply because of the fear of a little embarrassment, but just as the train was shutting its doors I peered out and there it was, 168th Street. "Oh dear!" I said. "That was my station and now I have missed the bus!" I was fit to be fled, and I had spoken quite loudly, and I felt extremely foolish, and I looked down, and the man who had offered me his seat was partly looking at me, and I said, "Now, isn't that silly? That was my station. A Hundred and Sixty-eighth Street is where I'm supposed to get off." I couldn't help laughing, it was all so awful, and he looked away, and the train fidgeted along to the next station, and I got off as quickly as I possibly could and tore over to the downtown platform and got a local to 168th, but of course I had missed my bus by a minute, or maybe two minutes. I felt very much at a loose end wandering around 168th Street, and I finally went into a rudely appointed but friendly bar and had a martini, warm but very soothing, which cost me only fifty cents. While I was sipping it, trying to make it last to exactly the moment that would get me a good place in the bus queue without having to stand too long in the cold, I wondered what I should have done about that man in the subway. After all, if I had taken his seat I probably would have got out at 168th Street, which would have meant that I would hardly have been sitting down before I would have been getting up again, and that would have seemed odd. And rather grasping of me. And he wouldn't have got his seat back, because some other grasping person would have slipped into it ahead of him when I got up. He seemed a retiring sort of man, not pushy at all. I hesitate to think of how he must have regretted offering me his seat. Sometimes it is very hard to know the right thing to do.”

“Livia.” He seemed thrilled to let the word roll off his tongue. “Do you know that I’m invisible?”“No one has really seen me in years.” Blake looked at the sky. “Sometimes I wonder how they know I don’t have a home. I try to dress decently.” He waved a hand at his jeans and army jacket. “I think it just seeps out of me. I’m not the same as everyone else.” He shook his head, his eyes reflecting a weary despair. As he looked at Livia again, the despair was chased away with a grin. “But when you saw me for the first time, you actually saw me. You saw me, and then you smiled like I was just the same as everyone else on that platform.”
