Have a relative (say, a mother-in-law) that invites themself to your home for a week. From overseas. Enjoy a first conversation that goes something like this:
"Hello! How was your flight?"
"Oh, you know, I don't think they have enough bathrooms on the plane. It seemed like there was a line the whole flight."
Come home at midnight from work to find the freezer door open - and everything melted. Or thrill at the sight of their hand touching every ice cube in the ice cube maker tray ("the dispenser doesn't work fast enough" was the comment).
There's more, so much more, but what a great motivator to get outside and do some walking.
