Ok it's simple, we all do things that other don't like.
For me, I leave cups on my computer desk. Sometimes I use one for water and I end up getting another and another until they are like 5. In the end I clean them up when people complain
Well..its not a habit but..when I use to ride a motorcycle. Female friends and family hated it. I had to get rid of both because I couldn't live with the fact that every time I ride with a smile on my face, I have people worried to death crying over it. Fukcing sucked, buzz killers.
Being awesome. My family and friends hate that I am so freaking awesome at everything I do. Work, running, racing, checkers, sleeping, eating, typing, breathing. I'm just so awesome they all hate me for it. Pure jealousy.
