My biggest weaknesses are music and anything clothing related.  Music because I have really terrible taste in it - I was once banned from using a jukebox - and clothing because I really lack the language to differentiate between lots of different articles of attire.  I think in the last run of doomtown someone had to nudge me hard in the ribs because I had suggested by accident that they were wearing their dress inside out.  (Which now finally clarifies for me the age old question of 'what's a petticoat?'  I had actually thought it was one of those tiny coats women wear over a dress... which is probably why readers might have been confused by my describing it wrapping over someone's shoulders while they walked down a street.)
