Why are you angry with people?

people get angry when they get bothered and just want to be leave alone ....but really you shouldnt get angry because that can cause you alot of stress even if its for a little reason....like when girls get their monthly thing they say your so grumpy but you shouldnt let people or things to handle your emptions you should handle your own emotions....or when boys are stressed because of work all they really need is a lil moment alone and a lil nap or a massage...
