Why did Lencho’s happiness change into deep concern?

Ans. As Lencho had predicted the rain did come. At the meal time, it came in the form of big drops. Naturally, the rain gladdened his heart. He could see better prospects of a good crop. However, his happiness was short-lived. Suddenly, a strong wind began to blow. The rain turned into big hailstones. The falling of heavy ball of big hailstones for an hour completely destroyed everything— leaves, trees and the standing crops. Naturally, such a heavy loss put Lencho into a deep concern.
