Symptom of inferiority complex.
"Over compensation: One of the most famous defense mechanisms people use to hide their inferiority feelings is to act superior. Not only will those people act as if they are superior to others but they will also devalue anybody who doesn't treat them as if they were superior. By doing so they can protect their ego by considering anybody who doesn't think that they are superior worthless!!"
You can deal with this issue as you see fit, but as for me, I see it as pointless to continue any discussion with you.
To Jim, thanks for your words, but based on above, probably not going to work. He needs plenty of time with a professional.
