       One afternoon, in Paris, I took a trip to an art museum while waiting for my husband to finish a

business meeting. I was looking forward to a quiet view (看) of some great paintings of excellent artists.

       A young couple looking at the paintings in front of me were talking non-stop. I watched them a

moment and decided she was doing all the talking. In fact, I was surprised at this man for putting up

with her everlasting speech. Bored by their noise, I moved on.

       I met them several times as I moved through those rooms of art. Each time I heard her voice, I

moved away at once. 

       I was standing at the museum gift shop buying some cards when the couple walked to the exit

(出口).

       “He’s a brave man,” said the shop assistant. “Most of us would give up if we were blinded

at such a young age. But he and his wife come in whenever there’s a new art show.”

       It explained the non-stop talk! A sudden sense of shame came to my heart for what I was thinking

just now. “But what does he get out of the art?” I asked.

       “His wife describes each painting so he can see it in his head.”

       At that moment I realized what is patience, courage and love. I saw the patience of a young wife

describing paintings to a person who can’t see and courage of a husband who would not allow

blindness change his love towards art. And I felt the love shared by the two as I watched them walking

away holding each other’s hands.
