My dh has a brother who is in his twenties. He is close with his brother, especially one of his brothers and this brother has been so friendly and caring with him lately but BIL can be a total PITA.
He can be such a bigot, he jokes about the disabled. He actually has a disability himself, but jokes about people who have a different disability. He jokes about the elderly. He jokes about the people he considers ugly and so on.
Unfortunately he can be very snobby and considers himself to be superior to everybody else and he is a potty mouth. Sometimes I think he likes „playing a role“ cause he cannot possibly be that snobby.
However dh loves him dearly, trusts him. Dh does not trust many people and the brother was sensing dh was not feeling well and was so friendly with him.
I think he is making an effort to be nicer lately but actually I still feel that I cannot stand him... but feel I should like him.
