<Recipient Address Goes Here>
This letter is to formally apologize to you for my thoughtlessness. I certainly should know better than to participate in idle gossip. It was immature, unkind, and foolish of me to talk about you and your business with someone else. I am terribly sorry. I realize I've hurt your feelings and I hope you will be able to forgive me. I promise that I will never let this happen again.
