2. Bring a towel, and most important
3. Don't panic!
I was first introduced to the book by my junior-year roommate, Jack. Wonder where he is. Great guy, but hard to get to know and was sick constantly. He was supposed to become a schoolteacher, but I don't know if he ever did. I borrowed his refrigerator my entire senior year, but he never visited the room. I returned it after graduation at his parent's house and that was the last I saw him. Hope he's all right.
Jack once had an ear infection and drank an entire bottle of Jim Beam to numb the pain. And this was a man who almost never drank. He was a big guy, nearly 300 pounds, and the only evidence he had been drinking was the empty bottle. He had an IBM Selectric that he let me borrow. He went home every weekend and never, ever went out any night while at school. He'd wake up in the morning, turn off his alarm and grab a book and start reading. This was before he'd get out of bed. As I said, he was sick large chunks of time. God knows how he graduated.
Funny thing was he was often sick in high school, too. (Yeah, we went to the same high school.) Missed a whole year I believe with some nasty disease, rheumatic fever or something.
Peach of a guy though. Here's hoping he's somewhere in the universe with a towel and not panicking and carefully explaining that 42 is the answer; it's the question that's the problem.
