While on a South Pole expedition, British explorer Sir Ernest Shackleton left a few men on Elephant Island, promising that he would return. Later, when he tried to go back, huge icebergs blocked the way. But suddenly, as if by a miracle, an avenue opened in the ice and Shackleton was able to get through. His men, ready and waiting, quickly scrambled aboard. No sooner had the ship cleared the island than the ice crashed together behind them. Contemplating their narrow escape, the explorer said to his men, "It was fortunate you were all packed and ready to go!" They replied, "We never gave up hope. Whenever the sea was clear of ice, we rolled up our sleeping bags and reminded each other, The boss may come today."
