People whizzing down the stairs first thing in the morning, fully dressed, with a bag over their shoulder (or a backpack;) grabbing a piece of lightly buttered toast from the toast rack - and waltzing off out with it. They don't sit down to eat it, they just walk out of the house with it in their mouth!
Never in my life have I ever seen anyone do this, and I've never done it myself. Who swans out of the house to the car, or the bus stop, or to walk down the street whilst munching on a piece of buttery toast? 😆
