I got him on his own today and broached the topic. He seemed to find it very funny. grrr.
I said "if you feel I am dressed inappropriately, can you raise it properly and not with rude tit remarks in front of a VI Former."
He said "you weren't dressed inappropriately, it's just you looked as if you were going to fall out of your top. It wasn't unpleasant, actually" and laughed.
So there we have it. Fcuking waste of time, no? ? I now have the choice of either a) boiling to death in the summer or b) having tit jokes made all summer. What a selection.
