As far as being passionate about something they're terrible at......I could probably be ok with that depending on what it is. I've met people before (Girls even) that love football for example, they think it's the greatest thing in the world and always have to watch the game. I don't give a crap about football so I just stay out of anything football related. I don't think it would be too different if someone had a hobby they sucked at that I wasn't interested in anyway.
