this happened in my history class on Friday.
Teacher: Let's play a joke on Sammi when she comes back from the bathroom.
Students: What is it?
Teacher: Well I'm rescheduling your test from Monday to Wednesday..
Teacher: But when Sammi comes back in I'll say it's rescheduled to today.
Students: HAHAHAHAHA THAT'S SUCH A FUNNY IDEA!
Me: I don't know, Sammi takes stuff pretty seriously.
Students: Shut up, Charlie.
*later*
Sammi: *walks in*
Teacher: Okay guys put away your homework, we will start the test.
Sammi: What? I thought the test was Monday!
Teacher: Yeah but I just rescheduled it. Sit down.
Sammi: But I haven't been here the past few days and I'm gonna fail.
Teacher: Well you should've thought about that before you decided to be sick.
Sammi: *almost in tears* But if I fail this I'm going to fail this class, I barely have a C as it is.
Teacher: Well you should've studied more.
Sammi: *crying*
Teacher: HA JUST KIDDING WE TOTALLY FOOLED YOU.
Sammi: *cries and runs to guidance*
and that's what breaks my heart about some of the terrible teachers our school system has
