Some teachers like to embarrass kids

That's really weird that one would think that teachers do that to embarrass people

Yeah, no. People who don't have good communication skills only get better by communicating.

So students who do not lift their hand should be left alone?? No incentive to study??

Or, y’know, people are too lazy and can’t be bothered, in which case they should be called on

Dear teachers,
If a student hasn't asked you to quiz or test them on the material yet, they clearly don't want to be tested.
It is my legal right to not take a test if it makes me nervous.

From everyone has anxiety
Well guess what? Not everyone has anxiety and you can't use mental illness as an excuse for your laziness and everything

Then there are parents that constantly ask the teacher to ask their kids more. Especially rich parents, the ones that think there is nothing wrong with their kids, feels the teacher is not giving their child enough chances and exposure.
