That is wonderful! It reminded me of a boyfriend I had who slipped in some ice downtown getting up a curb/crossing the street and a bus came along and didn't see him, would have run over him if a bystander hadn't pounded on it and stopped it. My boyfriend was horribly shaken for a week, kept describing how he saw the wheel/tire coming for his head, etc. Needless to say, I was very grateful for that observant person who worked to help! Your good deed didn't just help you and the older gentleman, it helped all who know/love him. Good "example" for me to follow too! :-)
