I do not repeat myself.

So, kids right?
If its one thing I've learned from teaching, it's that kids will mimic your every move. The reason they tell you to get the fuck out their face? Yeah,they heard it from mom/dad/grandma/neighbor, whoever. Half the time, they don't even know what they're saying, they just know it sounds badass.
Because of this, I rarely get mad about some kid shouting overheard phrases. I think it's kind of funny. Like a screwed up version of playing house.
Today, 4th period.
Me: Chelsea, so you'll stop talking, you need to move to a different seat.
Chelsea: I DONT WANT TO!!
Me: *blank stare"
Chelsea stands up, but instead of moving to the appointed seat, stands in the corner.
Me: If you can't sit down in my room, I guess you can't sit down on the bus to the field trip Wednesday.
Chelsea: I DON'T CARE!
Me: oh, that's good then.
Chelsea: *mumble, mumble*
Me: what?
Chelsea: I already said it! I don't repeat myself!
Me: *rolls eyes* that's nice. I do. You're not going on the field trip.
Chelsea: *mumble, mumble*
Me: what?
Chelsea: I already said it! I don't repeat myself!
Me: what?
Chelsea: I said I don't repeat myself!
Me: Oh, right.

and the reason I love my 7th graders is that they all got it and died laughing.
