Can you solve this mystery?

Son fiddling with the hot water heater.

Hose connected to hot water heater.

Hose traveling through the window,

to the below freezing outdoors,

into the hands of husband,

who is on the ice, making it smooth. He’s filling in the valleys and diminishing the mounds. All so that his children may skate with ease.

Mystery solved.

Time to bring the hose inside.
