What good is a relationship in which both parties always agree? In my opinion...it's a useless relationship, because you never learn anything from it.
Arguing teaches you patience and it teaches you forgiveness. It teaches you when to back down and how to appropriately deal with issues.
It teaches you that people can disagree...but still love each other. It teaches you that people don't always have to see eye to eye, in order to respect each other.
It teaches you when and how to admit that you are wrong...and it humbles you, when you apologize.
I'm glad that we argue...because it teaches me. I want to learn with you, forever.
