When this happens some amazing stuff starts to happen around the house. Forget being able to watch what you want on the telly and not having to wait for the toilet. Apparently the biggest changes involve water and cups.
More specifically, when you have a shower the water doesn't turn to ice after thirty seconds and there are always clean mugs available for cups of tea and coffee.
I asked Tracey what she was most looking forward to when the kids leave home and we finally become empty nesters.
"Getting my own room," she said. She's such a kidder. That she says it with a deadpan straight face makes it even more hilarious.
For our friends, these huge lifestyle changes became more apparent this week when one of their daughters popped home for a few hours.
While mum & dad prepared dinner, the daughter jumped in the shower, after which they all caught up over the lovely home cooked meal.
It was only after they'd waved her off they realized they'd been left with a sink full of dirty dishes: and only after they'd cleaned up and were preparing for bed they realized all the hot water had been used up in their daughter's twenty minute shower.
But then I imagine that's why parents love when the kids drop home once they've moved out - it reminds them how fortunate they are the buggers left at all.
