"Dear Susan- It has been a few months since I got married and I finally have some time to sit down and write to you. I just wanted to express my gratitude to you for being a part of my wedding. I had never ridden a horse before and you provided such a gentle creature. It truly made our wedding memorable and special. Moreover, I really appreciate your professionalism. You were very easy to interact with and were very accessible. You got things done quickly and you were punctual and flexible on what turned out to be quite a rainy day. Thank you again!"
