My Little Sister's Obsession with My Stuff

So here’s my confession, I secretly hate how much my little sister is obsessed with all my stuff. I mean, yeah, she borrows a lot of it and brings back some pretty funny stories about the time she used my old phone to call our grandpa as me, but honestly? It’s just getting ridiculous now that she keeps leaving everything scattered around like no one else lives here. Last night, I found her playing video games on my console with my favorite controller. Seriously, folks, am I the only one who feels this way about a sibling borrowing your stuff to the extreme? Anyone have tips or is it just me?
