It was a school trip. My friends and I were taking photos in the street of Vienna, trying to record the beauty of a foreign country. The change in climate had made my contacts(隐形眼镜) dry out quite often, so I was wearing my glasses.
But I didn't think the glasses looked good on me, so for any photo I was in, I would take them off. When I took them off in front of Vienna State Opera, I heard a tiny "ping!"—a screw(螺丝) fell off my glasses and they separated in half.
Hurriedly, my friends and I began to search for the tiny screw. We looked everywhere, but it was nowhere to be found. I was close to tears. How could I enjoy the rest of my trip if I could see nothing clearly?!
Just at that moment, my friend saw a store with a sign in German whose windows were full of various pairs of glasses. To try our luck, we raced into the store. Not speaking any German, we did our best to explain the situation. A friendly old man smiled gently and took my glasses into the back of the store.
After a while, he came back into the room. Smiling softly, he handed me my glasses, fully fixed. I tried to ask the man how much it would cost. However, the man just smiled at me and said, "For you? I will do it for free. "
That is the kindest thing a stranger has ever done for me. While I was in a foreign country and unable to even speak his language, this man, with a business to run, still gifted me that tiny, necessary screw —thus the ability to see for the rest of my trip and also a memory to be treasured.
