“For every minute you are angry you lose sixty seconds of happiness.”
― Ralph Waldo Emerson

In as much as possible I don't want to hear people shouting at each other.

This reminds of a post on FB about a father and son conversation on being angry. I can't remember the whole conversation but in essence the child was asking why do couples shout at each other when they are mad - that seems like they are talking to another person from afar. The father explained it and gave example.

Talk calmly. We don't to shout when talking to other person be it your friends, family members, and the likes. We don't want to push them away.
