Yesterday, as I sat in my son's karate class reading a book, I started noticing that I was getting odd looks from a couple of other parents watching the class. I brushed it off at first, but it was hard to ignore.
Then it dawned on me. I was reading "Using SOAP," which to non-techies surely looked like a primer on keeping clean. As far as they were concerned, I might've well have been reading "Deodorant for Dummies."
