Every house has one.
Some rooms are wrong and nobody can say why.
The spare room nobody sits in, though there's nothing actually wrong with it. The waiting room that turns an hour into three. And the opposite — a friend's kitchen where everyone ends up, every time.
Architects call it genius loci. Old term, no use at a dinner party.
A room you live in for a year has had a thousand goes at you. Almost nothing that goes on a wall is designed for that.
