0Vyger 9 years ago You are probably meaning some people and not all people. What is your definition of rude? Some people are raised to be rude, sometimes because that is the way their parents treated them. Some people adapt it as a behavior because they think its cool and gives them an edge in life (It doesn't) . Some people are rude as a defense mechanism, they attack other people so as to hide their own flaws and insecurities. The list goes on. The best defense is to not enable them by letting it bother you. I just smile at them and it often infuriates them. Nothing makes a rude person more angry than to know the only social skill they have has no effect on you.
