My Little Sister's Doll Collection is Starting to Creep Me Out

Ever since my little sister got into dolls, she’s been collecting them left and right. She has a whole room dedicated just to her dollhouse and all the accessories, like clothes and furniture. It started off cute and quirky when it was just two or three dolls, but now there are over fifty of them. I think they're staring at me with those creepy little painted eyes! Every time I pass by her room, I swear she's making new ones appear out of nowhere. Mom says it’s healthy to have hobbies, but honestly, this is getting way too much for me. Plus, the amount of space she takes up with her dolls feels like it’s encroaching on my personal space in our shared room. I hate feeling jealous or annoyed about something that’s not hurting anyone, but seriously, fifty dolls? What’s next?
