This is a great point. The term misunderstood indeed implies that something is not being understood correctly. Being misunderstood can be frustrating. You were trying to help the lady to clear her intentions which is actually a good empowering approach. Sometimes, pride swallow humility. We end up in situations like yours. I appreciate to you for taking high road and apologizing. I hope things smothed out with your friend afterward. Thanks for invitation. Good luck and keep shining!
