What's the sweetest thing you've ever done, or the sweetest thing done for you?

The sweetest thing anyone has ever done for me was actually something my hubby did for my mother. When she was very ill and living in a nursing home my husband would go out for a visit and give her a back rub to make her feel better. This was such a comfort to her during the last few months of her life. I will always be grateful to him for his kindness.
