Try not to take it personally because most likely he grew up in a family where anything he said was dismissed or taken wrong. He probably carries a sensitivity from that he is unaware of.

Actually, my brother in law passed a comment during Thanksgiving about the attitude of individuals who have their PHD. They tend to have this entitled way about them, deem themselves as a know it all when there is much they DO NOT KNOW. Often all they know is about themselves in their own knowing and they lack in their skills to interact with others allowing these others to have their own identity and give them respect. My brother in law is a professional and this type of individual tends to rub him the wrong way because they can get condescending and detached in an entitled way.

This kind of individual actually tends to have a low EQ. They tend to make awful parents because they are too controlling and don't allow their child to form their OWN identity.
