Dear Walt,
I am writing to express my heartfelt gratitude for your help. I am referring to that unfortunate accident the other day, when I was knocked off my bike by a taxi.
Most importantly, if it had not been for your timely assistance in giving me first aid, I fear that the consequences might have been much serious. Everyone agrees that it was your quick-witted response in that emergency that has led to this satisfactory outcome. Although nowadays people in mounting numbers talk about the need to be unselfish, we see very few people practice what they preach. If there were more people like you, this world would be a much nicer place.
My thanks to you for the help you render me are beyond words.
Yours faithfully,
XXXX
