You're lucky, mine was pretty bad. I had one that would get really annoyed when I had to ask her to repeat something. She knew I was partially deaf and would always have some comment like "Ugghhhh, if only you could hear better, maybe I wouldn't have to give some of my lecture twice."
Another one I had would call some of the maps I had to draw " dumb looking" or " I don't want to out this up on the wall with the other maps" because I'm colorblind and really struggled with getting the correct colors on the map.
