Ripping The Ripper

The student who ripped me off for $10 in the candle fundraiser says she is moving. I think that's a bit extreme to get out of a debt, but perhaps this time it's not all about me. Thing is, she says I should be nice to her because she is leaving. I say she should be nice to me, because she ripped me off for $10.

Hey, I lost it.
That's not my problem.
It's not MY problem.
Yes, it is. It was your responsibility.
Well, I'm going to pay you back.
Anytime.
Won't you miss me when I leave?
I don't know. It depends on if anyone else takes $10 from me.
You should throw me a party.
I just might. After you leave.
How's that a party for ME?
Well, when you pay me back that $10, I can spend it on a party for the class.
But I won't be here.
No, but it will be your party.
How?
It will be your gone-away party. In your honor.
But it won't be a party for ME.
Yes, it will. We can all enjoy your party after you're gone. Except maybe YOU.
You're mean.
I'm $10 poorer than I was at the beginning of the school year. That makes me mean.

Which may sound kind of cruel, but she didn't have to 'lose' my $10 and then tell me that it was stolen and then tell me it was lost and say she's going to pay me back when she's had a month to do that already and then act like it is totally no big deal and I should just forget about it and not expect her to pay.

Try that in the real world, girly. I'm teaching you a life lesson. People do not react kindly when you rip them off.
