An old woman had two large pots, one on each end of a pole. She carried the pole with the pots across her neck.

One of the pots had a crack in it while the other pot was perfect and always delivered a full pot of water. At the end of the long walk from the well to the house, the cracked pot arrived only half-full.

For two years this happened daily, with the woman bringing home only one and a half pots of water. Of course, the perfect pot was proud. But the poor cracked pot was ashamed of its own imperfection.

One day, the cracked pot spoke to the woman by the well: “I am ashamed of myself because this crack in my side causes water to leak out all the way back to your house.”

The old woman smiled: “Did you notice that there are flowers on your side of the path, but not on the other pot’s side? That’s because I have always known about your crack, so I planted flower seeds on your side of the path. And every day while we walk back, you water them.”

“For two years I have been able to pick these beautiful flowers to decorate the table. Without you being just the way you are, I would not have this beauty.”

Each of us has our own cracks. But it’s these cracks that make our lives together so interesting and meaningful.
