There were a few teachers who just did not like me because of my face. Once I was told to stand in the corner until I cheered up. The attitude was 'Oh for God's sake what's the matter with him?' But it's just a natural expression.
I've never heard my dad say a bad word about anybody. He always keeps his emotions in check and is a true gentleman. I was taught that losing it was indulgent a selfish act.
