I am 52 years old I would like to know the personality traits of certain people namely those who always speak ill of others , use an opportunity to find fault , always have a superiority complex. Think only they can do the work . Even while selecting an item for a memento only their choice is right . Claim that they have high level connections. When someone gets an award or a job/admission to institution of higher learning claim that because of their influence it happened though they had no role in the same. Do not speak or say hello to people whom they thing are far below their social level.
