Another jealous girl. She's lucky you're nice because if she would have gone through my purse she'd be seeing stars right now!!
I probably would have drawn the line at some stranger rummaging through my purse too. That kind of behavior is tactless and tasteless. Some people who are like that might mistake your composure for weakness and they might press harder to hit a nerve the next time an occasion arises. I wouldn't be leaving my bag laying around unattended.....people with that kind of brass are capable of worse things than rummaging through your bag.
