“Some things are governed by common sense. Putting buttons on the front of a shirt is a matter of logic, since it would be very difficult to button them up at the side, and impossible if they were at the back. “Other things, however, become fixed because more and more people believe that’s the way they should be. I’ll give you two examples. Have you ever wondered why the keys on a typewriter are arranged in that particular order?”

“Have you ever wondered why the keys on a typewriter are arranged in that particular order?” “No, I haven’t.” “We call it the QWERTY keyboard, because that’s the order of the letters on the first row of keys. I once wondered why it was like that, and I found the answer. The first machine was invented by Christopher Sholes, in 1873, to improve on calligraphy, but there was a problem: If a person typed very fast, the keys got stuck together and stopped the machine from working. Then Sholes designed the QWERTY keyboard, a keyboard that would oblige typists to type more slowly. ” “I don’t believe it.” “But it’s true. It so happened that Remington—which made sewing machines as well as guns at the time—used the QWERTY keyboard for its first typewriters. That meant that more people were forced to learn that particular system, and more companies started to make those keyboards, until it became the only available model. To repeat: The keyboard on typewriters and computers was designed so that people would type more slowly, not more quickly, do you understand? If you changed the letters around, you wouldn’t find anyone to buy your product.” When she saw a keyboard for the first time, Mari had wondered why the letters weren’t in alphabetical order, but she had then promptly forgotten about it. She assumed it was simply the best layout for people to type quickly.”

“Scolding must be very, very fun, otherwise children would be allowed to do it. It is not because children don’t have what it takes to scold. You need only three things, really. You need time, to think up scolding things to say. You need effort, to put these scolding things in a good order, so that the scolding can be more and more insulting to the person being scolded. And you need chutzpah, which is a word for the sort of show-offy courage it takes to stand in front of someone and give them a good scolding, particularly if they are exhausted and sore and not in the mood to hear it.”

“Some people like to push my buttons!!! I just wish they would give them back...”

“Some things in life only happen once, the memories of them lasting forever. They're moments that alter you, turning you into a person you never thought you'd become, but someone you were always destined to be. There's no magical rewind button in life, no take backs or do-over's to fix things you wish you could change.”

“Nobody ever feels just one way about another person, Margo. We're so much more complicated than that. I can see a million things you want from me, just like the million things I want from you. Some of them are wonderful. Some are awful. Some contradict each other, and some don't make sense at all. But none of those things matter, not really. What matters is what you do about them.”
