One grandson, who`s 18 now, has always bought us a present, since he was quite young, this year it was a doormat with Grandma and Grandad, spoiling grandchildren 24 hours a day, written on it, with a pic of an old couple, and 2 others started buying for us when they were about 20.
Boggles, your post made me think of our eldest daughter, when she was small, she had a thing about writing pads and pens for presents, another daughter bought tubes of Polo mints for me and boxes of matches for her dad, wrapped up in Christmas paper!
