Jonathan Trott is on holiday with his family. They decide to play table tennis – winner stays on.
After Trott has won the first 18 games, Mrs Trott quietly suggests that he might like to find a way to let the kids win a couple. Trott says no.
After 86 games, the family ask if they can stop and do something else instead. Trott says no.
Two weeks pass. The Trotts do nothing but play table tennis. Trott never drops a single game and the rest of the family are utterly demoralised by the experience. For his part, Trott feels immense satisfaction with his performance.
