Walkaround I was going to quote bits of your post, but my comments really all came to the same point: you don't believe the OP/the OP's daughter/both.
Were the other teachers unaware, or did he not actually walk into the room all on his own while the girls were asleep?
This assumes that the OP/her DD has lied. Why?
You can automatically assume this is due to an insane, power-tripping, misogynistic, inappropriately behaved teacher
And now a lot of hyperbole pointing in the same direction of travel.
When you strip away all of that, this is about a very simple incident: a male teacher walked into a girls dorm room to wake them.
This is against all the safeguarding I'm familiar with.
Why is this so hard to believe? There is a knot of posters that either refuse to accept that this simple incident happened at all, or that if it did, what's the fuss about?
There's a bit of Men Can Do No Wrong around lately, I agree with a pp.
