The bus was crowded with boisterous children, many of whom TJ seemed to know. He exchanged pleasantries of the spitball and ear-flicking variety with them. Fortunately, I was more or less left alone, and TJ made no effort to introduce me to anyone. Although I noted the lack of traditional social grace (something of which I was almost as guilty), I did not dare hold this against him for fear that he might detect even my most secret disapproval. In no way did I want to increase the likelihood that some subroutine of cordiality, constructed passively by observation but unused to date, would become active in TJ and lead to my forced interaction with the other riders.
