When J begged me to sleep with him I asked whether he had been unfaithful to his wife in the past. ‘Several times’ he replied. It appeared that he got up to all sorts of mischief on lads’ weekends away and assumed that I would also be game. I was not.

I didn’t tell his wife about this when I saw her later. Instead I despaired at her woeful skills of organisation. We almost reached the tube system before she realised that she had left my green handbag at her flat and had to go back to fetch it. This meant we wasted Oyster card card credit going in and out the barriers unnecessarily.
