Damn, teachers are hard to teach. I know exactly what you mean except mine were younger. Some were acting like kids.
Seriously there is that saying that you turn into the people that you are around most and they are all elementary teachers. One woman was answering a question that I had asked to the class and some teachers thought that it would be a good idea to make some pig sounds (not even behind her back) while she was answering me. They thought that it was so funny and it was so annoying. I nearly blew a fuse.
I will never teach teachers again!
BTW they were doing that correcting thing as well. I don't correct everything 'cas it takes too long and besides I want them to build up their confidence but a few teachers kept correcting each other, showing off how good they are. I made a point to correct them on everything they said and they got the point soon enough
