How can I theft proof my room?
My cousin has sticky fingers. She's been kicked out of my great-aunt's house, my grandma's house, and even her own home because she steals all the time. Now she's living with me and my grandpa. I've caught her trying to sneak into my room twice and she asks to borrow things that she shouldn't even know I have. For example; she asked to borrow my iPhone charger. I don't have an iPhone or even and iPod. I do have an iPhone charger, but I keep it in one of my drawers. How did she know I had one?
I've found an adapter that I had been missing underneath the couch cushion where she sleeps. I don't like people stealing from me, but my grandpa just turns a blind eye. To make things worse, my door doesn't lock and it can actually be just pushed open. How can I protect my stuff?
