In my day, the principal concerns of university students were sex, smoking dope, rioting and learning. Learning was something you did only when the first three weren't available.

What this means in practice is that if you are not a born worrier you have nothing to worry about (though of course you wouldn't be worrying anyway), whereas if you are a worrier by nature there is absolutely nothing you can do about it, so you may as well stop worrying, except of course you can't.

Boston's freeway system is insane. It was clearly designed by a person who had spent his childhood crashing toy trains.

Being a pessimist is just such a gloomy way of looking at things, so I have to hope for the best - life wouldn't be worth living if we didn't have hope. And I also do think that human beings often do do wonderful, correct, brilliant things. So, on balance, I'd like to be optimistic about the future.

Even though sugar was very expensive, people consumed it till their teeth turned black, and if their teeth didn't turn black naturally, they blackened them artificially to show how wealthy and marvelously self-indulgent they were.

But that's the glory of foreign travel, as far as I am concerned. I don't want to know what people are talking about. I can't think of anything that excites a greater sense of childlike wonder than to be in a country where you are ignorant of almost everything. Suddenly you are five years old again. You can't read anything, you have only the most rudimentary sense of how things work, you can't even reliably cross a street without endangering your life. Your whole existence becomes a series of interesting guesses.
