The other thing is do I want to play her as a greedy thief who steals from her party members or gets the best loot before the other thief does or maybe a bit more jaded and wise beyond her years type of thing? Given her life on the cruel streets my guess is the latter. I may want to play her more of a spy/assassin type rather than a common thief digging through pockets for any old bauble. I will leave that to the other thief in the group. He is as dumb as a stump. He may be useful. If the other members play correctly they won't trust me but I don't want it to be too strained if that makes any sense.
At any rate, I am really thrilled to be playing again. The computer has been my DM for far too long.
