It was raining, and the dancers on the shore were working very hard, performing well in their transparent raincoats. However, the tour guide on the boat was extremely inadequate in handling the emergency. The activity was supposed to last over forty minutes, but at the beginning, the boat broke down and drifted downstream for more than ten minutes without power, causing everyone to miss the earlier performances. Most of the tourists on the boat were dissatisfied. To make matters worse, the boats performing later were in poor positions, and most tourists couldn't see them either. But the tour guide on the boat only said he hoped everyone would understand. How can anyone understand that?
