On the Job Sonambulism

About 10 years ago, the post office introduced new uniform shirts. They were blue, of course, with red and navy pinstripes. At the time, I refused to order them; getting knit polo shirts that had no pinstripes instead, because I had pajamas that looked almost identical to the new shirts. This fall I finally got one of the new shirts now that I can do my route in my sleep.
Thinking about that made me wonder whatever became of the pajamas. Because, really, why would pajamas ever wear out? Was I such a hard sleeper that the knees wore out? “Man, he’s such a heavy sleeper that the seams just popped.”
