Hi, I read the thread at lunchtime. I was having a bad teaching day and could just imagine saying something stupid myself. Its so unlikely this teacher just said that out of the blue to a motivated and hard working class. This really highlights the fact that parents have NO CLUE what is going on. I wish we could show them.
I don't think the version of events the OP in other thread describes is actually correct.
This is a thread about a thread. But as AIBU can sometimes be a world of its own I wondered what teachers here felt about the situation described in this area of the site - and in particular by the views expressed by some posters who have said that they're teachers.
It is of course, possible that the Original Poster may not be entirely kosher.
