Just venting.
I'm experienced. I have lots and lots (and lots) of strategies for promoting good behaviour, rewarding it and discouraging poor behaviour.
I have particular child who is quite hard work this year. Behaviour guru in recently to talk to whole staff about behaviour/golden time etc. Proximal praise highlighted as the key to getting through to some kids.
OK, I think. I do that a fair bit now, I'll do it more.
Child A starts fiddling/making a noise.
Me: Well done, child B, you are REALLY showing me that you are listening well.
Child A: (In a mocking voice) "oh yes, Well done, child B, you are REALLY showing me that you are listening well."
Gah! Wonder how the behaviour guru would have coped with that child. :)
Me: Ignore.....ignore.....ignore....
