I mean I don't think anyone here is THAT attached to their opinion. If it was a crappy session, it was a crappy session! I'm really amazed how deeply all of us have thought about silence and the completely different meaning it has for a lot of us. But it's just like a hunch.

I really just had a feeling that (I'm a teacher too) she was refusing to give you the answer before actually seeing if you could get it yourself. I mean, if a student thinks they can't get the answer, it is undermining their confidence to just give it to them without trying to find out what they know first.

Ps you are definitely not an idiot.
