One afternoon I toured an art museum while waiting for my husband to finish a business meeting. I was looking forward to a quiet viewing of the wonderful paintings.

A young couple were viewing the paintings in front of me and chatting with each other without stop. I watched them for a moment and noticed the man’s wife was doing all the talking. I was surprised to see that the man was so patient and could stand his wife’s words, but I still moved on.

I met them several times when I moved through the different rooms of art. Each time I heard she continued talking about the paintings, I moved away quickly.

I was buying some gifts in the museum shop when the couple came near to the gate. Before they left, the man reached into his pocket and pulled out something brown. He turned it into a long stick and then tapped(轻敲) his way into the coatroom to get his wife’s jacket.

“He’s a brave man,” a clerk beside me said. “Most of us would give up if we became blind at such a young age. During his treatment, he made a promise that his life wouldn’t change. So, as before, he and his wife come in whenever there’s a new art show.”

“But what does he get out of the art?” I asked. “He can’t see.”

“Can’t see? You’re wrong. He sees a lot , more than you or I do.” The clerk said, “His wife describes each painting, so he can see it in his head.”

I learned something about patience(耐心), courage and love that day. I saw the patience of a young wife describing paintings to a person who was blind and the courage of a husband who would not allow blindness to make his life different. And I saw the love shared by two people as I watched this couple walk away holding each other’s hands.
