“Oh fuck. It’s like period pain in my head. It’s toothache of the brain.”

“Patrick opens his arms about three feet wide and, with one finger pointing up on each hand, tries to show the scope of this thing. I notice that he doesn’t look at his hands as he does this, but at the wall behind me. It suddenly occurs to me that when people describe size this way, they’re relying on perspective to help them. He’s not saying ‘It’s this big.’ He’s saying ‘It would look this big from here if it was over there.”

“I can't fuck up his whole life and take away everything that means something to him just because I think I've found my soul mate.' 'Yeah, but...' 'Yeah, but. I know. Having found my soul mate, how cruel is it for me to stay with Bob, pretending I feel more for him than I do and preventing him from going out and finding someone who loves him the way I love Mark?'

“If you threw a brick at someone you would be responsible for them feeling pain, presumably,' Libby said. 'But if you do the right thing and it makes someone feel bad, isn't that their problem? Then again, how do you even know what the right thing is? Who decides?' 'It's so confusing. I am sure about Mark, but I was sure about Bob before that, and Richard before that. Maybe Mark isn't for ever, I just think he is now when I can't have him. I have to face up to this about myself. I fall in love like that.' She clicked her fingers. 'I always have. For other people, love is like some rare orchid that can only grow in one place under a certain set of conditions. For me it's like bindweed. It grows with no encouragement at all, under any conditions, and just strangles everything else. Good metaphor, huh?”

“Christopher, like most people, didn't like his universe being unfathomable, so I doubted that a Zen koan would help him.”

“Libby stood at the bar like something that had been hastily added at the end of a painting that hasn't quite dried yet.”

“But I quite like the way you can talk about science without necessarily using mathematics, but using metaphors instead.”
