My parents (well, mostly Mum) are always pleading for me to visit them at home, but i don't often get around to it (they live 4 hours away). When i do however, they don't do anything! They just carry on with their own lives and pretty much ignore me. I think it's like Ashley said, they want it to go back to when i was a teenager and they would weed the garden/ potter around the house, and i'd watch TV etc, then meet in the evening to eat dinner/ watch TV. That's what they remember, and that's what they expect. I don't want to drive for 4 hours to go and do that though, its annoying.
I don't find myself acting like a child though...if that's what the thread was about?
