Meh. Before D&D, I had a normal life, played basketball (usually at my dad's urging to help me lose weight; didn't helped) and watched Celtics games. I hang with friends who prefer the Lakers (the kind of friends who find D&D alien until they become adults), and always gather around the TV set watching them go head-to-head: Larry Bird vs. Magic Johnson. We trash-talked about whose team is best, yell at TV when the referee puts out a bad call or never call a foul, but all in all we had fun.
I also have friends that don't find sports interesting and that's cool.
