Peter, Gus, Tyrone, and Bob played a round of golf on Wednesday afternoon. After the game, they went to Tyrones house where they enjoyed some drinks on the deck, discussed their golf games, and watched the sunset. A prize of 5 golf balls was presented to Gus for winning the days round of golf. He was holding a glass of wine in one hand and collected the balls in his other hand. One of the golf balls fell, and bounced down the steps onto the grass. He stepped onto the edge of the first step and overbalanced/slipped. He fell heavily on his bottom, injuring his back seriously. The stairs consisted of two sandstone steps with no handrail. The deck was well lit but the grass area was not.
