Good to know you got yourself out of the situation. Funnily enough, I did exactly that too; I left it as it is and eventually moved on from where I grew up and lost contact with my friend.

Still, I've always felt a tingle of guilt every time someone looses something valuable at the cinema. It always reminded me that if everyone runs away from a problem, nobody will solve the issue. Being slightly older (and maybe wiser) now, what I should have done is try to find a way to convince her to stop stealing.

Anyway, thanks for your reply!
