Class Party

I didn't take French class, but I used to talk to the French teacher at my school because we both were French. When couple of kids told me that the teacher invited me to a French class party before winter break, I followed them to the classroom and began grabbing food from the buffet.

I went up to thank the teacher for inviting me to the party, but she just gave me one of the dirtiest looks ever and said, "Take your plate and leave the classroom."
 
It turns out she never invited me, and that a bunch of kids decided to pull a prank on me. I never talked to the teacher again.

And that's what stuck with me, even 12 years later.
