David was a little boy who befriended Sam Pearson in May 1982. David told Sam he was in for tests "for all sorts". Sam was intrigued by David's Rubik's cube but preferred to play draughts with David. David never had any visitors and he always ran off when Sam had any. Sam was shocked when he discovered David needed to have an operation and had been taken to intensive care, so he gave Sister Milner a chess set to give to David.
