WHAT'S WRONG WITH MY SISTER?!

she saw her hole puncher in my room, and she said i stole it. HOLE PUNCHER. its obvious that my mother put it here. she said i stole it. the problem is, whenever she see things in my room (she come often to use computer), she said i stole it. she everytime also said I STOLE THIS AND THAT. and guess what she said i stole? i stole her hole puncher, i stole her tissuebox (-.-), i stole her phone(because she was charging her phone an the phone was on the table).

can somebody please ask her to use her brain and think?

I'M ANGRY!!!
