Some studedt complained about me to a colleague. This is kind of a bummer. Although this wasn't explicit, I think implicitly I was hoping to go through the year without anyone ever saying I did a bad job.
The class was too loud so I gave two people extra exercises, and supposedly they complained that it was too much. But it was weird because my colleague said they thought they had to do three tasks, when the exercise was actually "here are three tasks, choose one of them". So it may have just been a misunderstanding. Also the third exercise was a logic puzzle that I didn't think they would be able to solve anyway (so if they really thought they had to do all three, certainly complaining would be justified). The task was meant to be something like "here is an easy fun exercise you can do in 5 minutes, if you don't want to do this, here's a totally boring exercise you can do in 15 minutes; also if you're smart you can instead solve this logic puzzle".
Also I think one of the two complained that they hadn't done anything wrong, they were just saying something about the material to someone else. Which is totally true, it's just like, when everyone is too loud, you have to pick out one to punish to make the others realize that you mean business, and that choice is going to be arbitrary. The crime wasn't saying anything wrong, the crime was talking too loudly
