WishIwasYounger, I too have wondered that. I'm an older gran of two boys who live quite a distance away and soon to be gran of a girl (first child of my only daughter) who lives ten minutes away. My knees won't be up to the horsey rides I gave my eldest GS (shouts of more, more & fits of laughter) but I will hunt for conkers, acorns, feathers and interesting leaves, read & make the voices, jump in puddles, listen, explain how to play cards, ludo, draughts, dominoes, go for walks, to the market, put flowers on the family grave, listen some more, answer questions, make gingerbread men for her daddy to eat, play at shops and tell her about my childhood, work, travels etc because that's what my grandad did for me (my grandma's both died before I got to know them) he taught me to ride a bike & my times tables! He taught me to be kind too and that is a gift that's timeless.
