Yeah, let’s not pretend that “normal” is some sort of awesome. One generalization I’d make about the homeschooled people I’ve met is that they seem to have a more confident sense of self. Probably because they didn’t have it squashed and beaten by 12 years of Lord of the Flies-crossed-with-Milgram experiment that we call public school.
That kid is missing out on stuff that is, let’s face it, not always that awesome. And he might be suffering now, but I guarantee if he gets away to college or somewhere normal for a job, he’ll be the coolest, most interesting person most people who meet him will have met.
