the way we get angry with people

i have noticed that most people do swear and curse when they get angry. i was not in a habit since i was young to say things like curses even when making jokes or just say it for no reason. i do consider it very serious thing to use those f*** words and other words like that for whatever reason. i have different way to show my anger or disappointment. i may put on angry face, but that's it. i may do say the things i feel but without those curses and f words. i just don't feel comfortable with those words and feel that they are very much unnecessary. most of the time i just walk out or just stay quite to the point you would know i am trying to avoid to talk because i am angry.
