The wedding was a long day and by the time the party kicked off in the evening, we were all flagging. There was a table at the back with four free chairs next to a pudgy woman in a cardy. My friend’s pregnant girlfriend went to sit down in one of the seats.

‘Those chairs are taken. All of them,’ the woman said.

I watched the table for an hour. The chairs stayed empty.

At the end of the night I saw the woman again. She was on a different table by the dancefloor, four empty seats next to her.
