Input: So a little background; My sister-in-law lives with us while she's in school. She's almost 21, doesn't have a license or car so she gets rides from us, doesn't pay for the gas, doesn't pay us rent, doesn't pay for the food she eats. She has a job, but it's a job at the school she goes to and anything she earns goes towards her tuition. She has taken and used my makeup so much, without even asking, that I had to move it out of the bathroom into my room, and she uses my shower and face products.

 She has also rented movies from my Amazon account without asking, when she has access to all the streaming services my husband and I already pay for. I am on a fitness program and have certain healthy foods I buy for myself that are more expensive. She has been eating them, and has even taken them and put them in her mini fridge in her room for herself to eat. In spite of all this, her parents still throw a fit and claim her as their dependent come tax season. Her parents have also taken money from us and wrecked my car w/out paying for it, but that's another story. 

So I purchased a locking shower caddy, put a pin on my Amazon account that has to be entered before purchasing, moved the rest of my toiletries to my room, and bought my own mini fridge with a lock where I will be keeping all of the foods that she regularly takes/eats from our fridge. If she gets hungry, that's her own problem. I know she gets a little money from the school to buy food from the store on campus. At her age I was renting an apartment, had a job, a car, and paid for all my own crap. I know that she doesn't have much money to buy her own stuff but she's basically a grownass woman that can't even drive, lives with us for free, doesn't have a regular paying job, and I don't believe she is entitled to my stuff just because she lives in my house and is broke. AITA for locking this stuff up to keep away from her?
