"As for adolescent talk, I've actually heard dumber excuses from a teaching professional, who bewilderingly worried about DD's mental state if her classmates grew breasts before her. In your case, would assure the teacher that my child is not being raised in a bubble, and regularly interacts with members of all age groups."

I had to come back and post on this thread. The 5th grade teacher at our last meeting cited the following concern for DS. (He is in 2nd and going upstairs to the top floor to 5th grade math.) She is concerned that he is "on too many floors" throughout the school day. He attends 2nd grade on the 1st floor, attends 5th grade on the 2nd floor and then goes to the basement floor for lunch. It's too much "bouncing around" the building and they are concerned about some potential mental unbalancing that could happen to DS.

Where's that thread on this website about ridiculous things that administrators/teachers say?
