A friend at school got me into it; although I think I'm the only one still playing from that crowd.
Having worked in a FLGS, while it was far from an every day event that someone would come in interested in roleplaying, or Dungeons and Dragons etc, it wasn't a rarity either. I guess maybe once a month or so someone would ask about it in some form or another, although it wasn't always a genuine interest (there'd be occasions when a parent wonders what their kids actually spend their time doing, for example).
