How to repair a relationship in one simple step

Are there people in your life who you care about and you don't talk to anymore?
Maybe words were said, or something hurtful happened, or a commitment wasn't kept.  Or you didn't call when you were going to, and as months or years went by it seemed more and more difficult to get in touch.  At some point, you become embarrassed because so much time has passed.  You don't know how you would start a conversation.
Have you ever thought about what it would take to repair the relationship?  Consider for a moment that it could be repaired with one simple action on your part.
It can begin with one phone call.  Or even a letter, if a call seems too hard.  You could apologize for your part in the conflict, if there was one.  Or apologize for being out of touch. You can let them know that they are important to you.  That you miss having them in your life.
It is possible that taking an action such as this would make no difference.  If that is the case, you are no further ahead or behind in that relationship than you are right now.  And you would know that you have taken an action to resolve something that was important to you.
Who could you get in touch with who matters to you?  Will you give them a call? I would love to hear how it goes for you.
