I'm currently reading Paul Feig's hilarious account of boyhood in the late seventies/early eighties in his book Kick Me. Feig is the creator of Freaks and Geeks, an amazing show that I highly recommend you watch. If you've already seen it, watch it again.
In the 1980s, the distinction between the various cliques was pounded into our heads via John Hughes - The Breakfast Club and Pretty in Pink are 100 percent about the caste system within the nation's schools - the rich, the stoners, the jocks, the geeks, the burn outs, etc.
The 70s certainly had their fair share of cliques as well. I definitely fell into the geek category until something woke up inside me (I'll let your imagination fill in the blanks) and got interested in girls and having a "good time". In one fell swoop, I put away my "childish things" - the Dungeons & Dragons, the Star Wars figures, the nerdy clothing - hit the roller rink and never looked back.
It wasn't till I'd been married ten or so years that my inner geek resurfaced. Once again, I found myself reading comic books, obsessing about Star Wars, and spending more time on the ol' computer. I'm curious what clique(s) the readers of this blog fell into back in their younger days. Drop me a comment, I'd love to hear it!
