Two boys in my class told me today that they heard our class TA (Miss X) say to another TA that I couldn't control my class. I'm so upset, for a start Miss X is a (supposed) friend of mine, I think it's so unprofessional that this could be overheard by the children, and it's really dented my confidence. I've never been worried about controlling them before, they are chatty, it was wet play all day yesterday so they were a bit doolally, but I feel really hurt! I feel this has ruined our last week of working together, I also don't feel like I can ask her about it as I'm too upset. Should I just forget it, how would you handle it?
