I've been called weird for my music taste (I tend to switch between electronic dance music and metal). And since I hardly ever listen to the radio or Sirius Hits-1 I don't know half of the names of the people who are popular in music right now. I can't say I regret it, though. It all seems to be the same bland pop-with-rap-and-hip-hop-elements anyway, and in 6 months most of those names will be forgotten.
Also, I'm more touchy-feely than most people are. I'll randomly poke people sometimes, or sneak up on them and hug them or lean on them or something.
