This piece of advice can be a game-changer and will help you calm down in the heat of an argument.
“In some situations, some arguments, you are not able anymore to control your words. So having a safe word is a great way to stop the escalation:
It gives a warning signal to avoid hurting each other
You can resume the conversation once both of you have calmed down
You should use an easy word to remember (fruits or vegetables for example)
It’s a way to say « time out » and to make sure the conversation won’t be counterproductive.”
