history: Well last summer while I was staying with a friend I went to the store to get some food.  I got the wrong change back and kept the extra $20 cause I didn't have a job yet. Last summer I stayed with a friend as I was nearly broke.  I went the store to get food and got back $20 extra in change from the cashier and ended up keeping the money. Oh wow_comma_ so it was extra money that was not yours?
current: Yeah so her drawer was short. I realized it later not while she gave me the change so that helped me justify keeping it.
next: I hope she didn't get in trouble for being short $20.
