This is wonderful, Harry. It is letters like this that are precious and prove to us that our life and actions have been worthwhile. Your program obviously made a huge difference to the lives of both Steven and his mother, and you should always be proud of that.
I am sure there are also many other generous things you have done in life that changed lives that you may not have had written acknowledgement of, but that made you feel warm and fuzzy and gave you a sense of achievement. We all need this.
Thank you for sharing.
