I've known her since we were at primary school.
Last time she came to stay, she said she wanted to talk to me about something 'really bad' that she can't tell anyone else. She told me she regularly shop-lifts (mainly clothes, make-up, costume-jewellery)! She then showed me a dress she'd stolen that morning while we were trying on clothes in a small local boutique! She didn't seem ashamed in any way, more pleased with herself. When I asked how how she managed it without me or anyone else noticing, she seemed really proud and went on to describe her techniques in detail. I was shocked, tried to reason with her (small local businesses suffering etc, the cost to herself if she gets a criminal record). She said she can't stop and doesn't want to, that she's been doing it for years and never been caught. She said its partly the thrill of doing it, partly that she always wants stuff she can't afford.
Now she wants to come and stay again. I want to see her but I'm really uncomfortable about the shop-lifting thing. And I can't help thinking will this addiction also make her want to steal my things too? Should I put my jewellery away, should I hide anything she might take a fancy to? Our guest room is also our storage room, so I keep a lot of my clothes, spare products etc in there. Or AIBU to trust her less?
