How can i prove she stole my stuff?

Okay, so my ex-best-friend stole my shirt and my lipgloss from my grandma's house when I had invited her there a while ago. I know because I saw them at her house, and they are the exact same things as mine were. Well, I asked her about it, and she...

denied it. I really want the stuff back, but I can't get her to tell the truth! What should I do?

You're 27. I know this is a sad situation, but think of it as a cheap price to pay to find out her true character.

With no proof, you have no options - you wouldn't even win in small claims - write it off, move on...I wish you the best !!

Again, you're 27. At least you know her true character, move on, buy a new lip gloss and I'm sure you'll find a better shirt that the one she took.

No, no, no! I am not 27! I was just bored, so I said I was 27! I am only 13!!! So, what should I do. This isn't just about the stuff, she always steals and lies and cheats, and gets away with it. I want to defeat her once and for all!
