Disappointment

What do you do when you say you'll do something? And then actually don't do it?. What I'm talking about is in relationships, often we say that we're going to do something and then something happens and we're able to follow through. When you're the one that doesn't follow through and someone is hurt or disappointed, how you behave. Do you defend or explain or do you own? When they say that you've done something that harmed them, no matter what you think about it, own it to start with, to see how it is to be in their shoes. And then if there's way to make it right, please do the best that you can to make your right I love you
