I am quite afraid posting this because my best friend's mom is actually a teacher and might misunderstand this (This is all imaginary I used myself as a reference)

my bestfriend would intentionally say something loud about me like " do you think I don't know what you do with boys and other stuff that can ruin my image apparently I never knew this can be a disorder and if I tried telling her she will get angry and she is teacher's daughter too which she thinks she can be just too proud of she goes on and on about it I never had a problem with it until that one time when I mentioned my mom she is a housewife btw and she was like what's there to be proud of and compared my mom to her mom I warned her and told her to fix her behavior but she started comparing my height,weight,skin colour and grades but she couldn't except that I was better in singing and dancing than her and would often get compliments about it she even  tried to persuade me to not sing...
