A man in India carried water using two pots. He put a long stick across his shoulders and hung a pot on each end. One pot had a crack（裂缝）while the other one was perfect. Every day, after walking from the river to his house, the perfect pot stayed full, but the cracked pot became half empty.
This continued for two years, with the man carrying only one and a half pots of water to his house. The perfect pot felt proud because it always did its job well. But the cracked pot felt ashamed（惭愧的）. It thought it was useless because it could only carry half the water.
One day, the cracked pot spoke to the man by the river, "I'm sorry. My crack makes water leak（漏）out every day. You work hard but get less water because of me."
The man smiled and said, "As we return to the house, I want you to notice something along the path." As they climbed the hill, the cracked pot saw beautiful flowers growing on its side of the path. But it still felt bad for losing water.
The man explained, "I knew about your crack. I planted seeds on your side. For two years, you watered them every day. Those flowers make the way to my house beautiful. Without your crack, this wouldn't have happened."
