The discovery of night-blind

I was studying at a key middle school in the early 1980s. At that time, where the key middle schools, state would fund them far more money than that of ordinary schools. Our school began build a large-scale buildings and the massive construction projects were here and there. So there pailed a lot of cement and sand at the school gate. One autumn evening, our class started the first day of going to night classes. After having my dinner at home, encountering with the sixty-seven the girls outside the school, we walked towards school. Walking to the school gate, we found the school ground was muddy than the outside after several autumn rains. But I did not understand why they did not choose the royal road but choose the muddy. I was a little angry and told them, "I don't like that mud road! Why not the royal road?" Then, I walked toward the white smooth place as quickly as possible. " How do I feel the feet of the water?" Just listened to the girls laughing and shouted, "Autumn, welcome to river trip, hmmmmm?"

As the saying goes, "the young people do not learn a lesson." After that "river trip" event, the next day was Sunday. In the evening, my mother and I went on the way home. That era, the roads were all dirt road. "What a day?" I thought, " it's raining again." Our road was full of mud. Suddenly, I saw there was a good flat road in front of me. So I told my mother, "Mom, I will lead you to the smooth road!" I grabbed her left hand and went on toward the royal road. Who knows, mom got rid of me and said, " I don't go with you. Look, the front is a large puddle." She advised me to follow her. I thought to myself, " It is obviously a smooth road!" I was a little upset and ran over and found another "river trip". Suddenly as if something hit my mind, and made me remember the same " river trip" last night. Finally, I asked my mother, " Why is my seeing things not the same as others? "Mother shocked and said" Ah, your father often escapes the shadow on the street at night, and sometimes bows drill that shadow! "
