At a recent wedding, I found myself trying to sweep my pants. I don't usually wear a kilt outside of the house - mostly because either I'm going to work, or riding my bike - but I always wear it around when my girlfriend is over. I think that since she was with me at the wedding, it triggered something that caused the sweep. I mentioned it to her and she said she noticed. She kept having to stifle a laugh everytime I went to sit.
