Step sister (11/f) keeps stealing my clothes what do I do is this normal.
So I (18/f) moved in with step family in may. My step sister (11/f) and I share a room just due to not having enough rooms in the house for the combined head count of 6 kids on top of my dad and his gf. It was about a month ago my step sister asked if she could borrow a pair of jean shorts I said yea and gave her a pair I didn’t care about. We get along really well and so I didn’t see why not. Well she never gave them back which ok wtv but then I notice she’s wearing a different pair of my shorts that I didn’t let her borrow like a week later.
I don’t mention it and let it slide. Then another pair of my shorts go missing. I don’t mention anything about it until 3 days ago I take my step sisters laundry out of the dryer to put my stuff in. I find one of my matching Victoria’s Secret sets that I don’t wear anymore cause the bra is now too small so ik for a fact it didn’t just somehow get mixed in with her stuff. And then found another pair of my underwear. I confront her about it but she says she just picked stuff up from the bathroom and washed it and doesn’t know why my stuff ended up in her laundry. So I say ok wtv. But then AGAIN today I find 2 pairs of my underwear in her dirty laundry which I didn’t wear and then another pair of my underwear in the bathroom trash??
Like there’s no way she isn’t going through my dresser. Is this normal sibling behavior? I’ve only had a little brother so I haven’t had to deal with this. It would’ve been one thing if it was just the shorts but underwear??? I also keep all of my dirty laundry in my clothes basket and everything clean put away. I’m really nitpicky and sort of territorial about my belongings so this is getting really annoying. It’s also awkward asl cause we get along with everything else.
I’ve already confronted her about it so idk what I should do. Should I go to her mom or just confront her again?
