Actual exchange between me and youngest sister

I went into the kitchen earlier for dessert. Opened up the chocolate creme Oreos, only to find two and a couple of broken halves. Knowing that my mom said she hadn't been eating them, and knowing that my dad doesn't really like cookies, I go to my sister's room.

Me: *raises middle finger*
Little Sis: ???
Me: *points to Oreo package*
Little Sis: That's right, I ate them, so fuck you!
Me: Fuck me? I BOUGHT the Oreos.
Little Sis: ...Yeah, I realized that.

It was actually pretty funny, but c'mon. She ate nearly all the Oreos on me.
