Dear _________,
A good friend is hard to find. And although we haven’t known each other for very long, I want to thank you for your act of kindness last week. You not only gave me your shoulder to cry on, but you patiently, and without judgment, listened to me ramble on and on as I tried to sort things out. This week I reached a turning point, and my outlook is now much brighter. I will always remember the sweet friendship you extended to me that night, at a time when I needed it most. Thank you for your thoughtfulness and support.
