"Maybe You're RIGHT!"

This phrase is highly effective in diffusing an argument and restoring frayed emotions. The flip side to "maybe your right" is the humility of admitting, "Maybe I'm wrong". Let's face it. When you have a heated argument with someone, all you do is cement the other person's point of view. They, or you, will not change their stance and you run the risk of seriously damaging the relationship between you. Saying "maybe you're right" can open the door to further explore the subject, in which you may then have the opportunity to get your view across in a more rational manner.
