Nobody is Perfick

I read this book of little vignettes by Bernard Waber over and over again when I was in first grade. I can remember exactly where it was on the shelf in the Denville Library. I find myself thinking of it often, but I never remember it very well, so I found a copy online. And there it all was -- children having frustrating and ironic emotional adventures, all capped off with the twilight zone tale of Peter Perfect, who does everything right, and everyone envies, until, well, that would be a spoiler.
