Thank you everybody.
Because I have such a thick skin - I didn't let her comments affect me; they only
superficially irritated me because she was so obnoxious.
If she thinks that any of those kinds of comments are at all "motivating" - well -
sorry - they are only annoying and recognized as demeaning.
Actually - we weren't at the end of a day - and I'm not slow.
I have never in my life encountered such an irritating "teacher".
