The mug sits unwashed on the kitchen table, a layer of white fuzz growing on the surface of the dregs of tea inside it. A smudge of lipstick is on the rim, and there’s a fingerprint made in chocolate on the handle.
The rest of the kitchen is pristine. Every single other mug, cup, glass, plate and bowl is dutifully washed, dried and put away immediately after use. But the mouldy mug remains on the table, as it has for three weeks now.
