If you're asking how to pickpocket in the game, you can do so once you have a high enough skill in the mischief trait, and you will only be successful if the person at least slightly kind-of likes you. I would do a few mischievous actions first (which for some reason most Sims like), and then try to pickpocket. It usually works if they're only slightly "in the green" with their relationship.
FYI, max mischievous skill gives you the "air horn" ability (not sure why that would be the max, but whatever). My evil Sim got that shortly before he died (of old-age run on tread-mill and then woo-hoo, of course), but he was pick-pocketing Sims long before that.

No, I don't think it has to be that high. I don't remember how high, though.
