Dear David Harris,
I would like to say thank you for all of your kindness and patience last Friday evening. As you can probably guess I don’t like going to hospitals but am glad that you made my time in the emergency room a painless experience. I would like to thank you and the other nurses for making my short visit a relatively pleasant one.
