I am 43 years old and still get gifts (Christmas and birthday money) from my grandparents. When I got married, they started sending gifts to my husband, who was incredibly touched. He says they don't have to do that and the fact that they do gives him the warm mushies. He lost all of his grandparents at an early age, so being adopted into the family as a grandson made him feel wonderful.
A few years ago my uncle was murdered. My grandparents were thousands of miles away and couldn't make it home for the funeral. They were both devastated and very distraught that they couldn't be there. My husband did not think twice - he travels a lot in his job, so he turned in his accumulated miles and got them two plane tickets home. He felt it was the very least he could do, and felt helpless that there wasn't something more.
