Feats of strength? Do personality trait strengths count?

If so, my greatest strength is complaining. I meet folks I haven't seen in a while and ask how they're doing. When they tell me "Okay, I can't complain." I always respond with "I can, and I'm very good at it."

Oh, and talking. I'm great at talking; I'm an Irishman after all (got the gift of gab). I'm not so good at listening, but talking I can.... Er... Okay, I'll shut up now.
