But while I was sitting down, I saw something that drove me crazy. Somebody'd written 'fuck you' on the wall. It drove me damn near crazy. I thought how Phoebe and all the other little kids would see it, and how they'd wonder what the hell it meant, and then finally some dirty kid would tell them— all cockeyed naturally— what it meant, and how they'd all think about it and maybe even worry about it for a couple of days. I kept wanting to kill whoever'd written it.
