She’s pouring toothpicks onto the kitchen table, to check whether the box is lying. You’re thinking about the tree outside the bedroom window of the flat you viewed that morning. The voice of the current owner says So lovely in summer, it’s got those little leaves that let the light through, and you turn around, because you thought you were alone in the room.

What are the limits of a house? Do they trace the outskirts of our imagination? Some sketch of BBQs on amber afternoons, workmates and football mates and dribbles of condensation sledging down beer bottles, of reading books by lamp-light, the soft patter of slippers across the hall, whisky-bringing, of rushed workaday mornings, dropping keys and forgetting umbrellas and a kiss before you go in case you die in a car crash?

When you look back at your mother she is crying.

There’s one hundred and forty three. It said one fifty. She looks up.

What are the limits of a house? A small, square room that whispers in both of your ears. For the baby.
