I went in to the laundry room at my apartment complex yesterday and said hello to my neighbor walking out. Once I set my basket down, I found a $20 bill on the ground. I assume my neighbor dropped it, but there's no way of knowing. Also, I don't know where that neighbor lives. My complex has like 300 units and the grounds are huge. I picked up the $20, but I haven't spent it. It's been a week and I haven't seen the neighbor. What do? Should I just call it found money and go minigolfing?
