To give an after school snack to your eldest, the sliding glass doors to the back garden framing his sturdy head as he bends over homework, the green of shrubs reflecting off the glare in his specs.
To peek in on the girl, sick from a cold, asleep in her own room, in her own bed, cuddled up to the hippo we left behind over two years ago.
They're all here, in our new home, breathing new life into these walls. Oh, we are cleaning mildew and a little concerned about the bird living in our chimney, and the toilets are a bit - how shall we say - wanting.
And now, I must wash the hippo. And the bedding. And every surface. Because now, we are home.
What's underfoot in your house today? Toys, illness, homework or mold?
