There are 2 ways..their ATTITUDES n the way they TREAT others i GUESS..but its hard to tell SOMETIMES. For example e.g. their attitudes maybe rude, impolite, selfish, but tat might be just how they are towards others normally..but if u judge them by the way they TREAT, u'll see it in a whole new perspectives e.g. Bullyin, helpin others out, caring, etc.
