 “BANG!” the door caused a reverberation (回声). It was just standing there, with father standing on one side, and I on the other side.

We were both in great anger. “Never set foot in this house again!” stormed father. With tears welling up in my eyes, I rushed out of the flat and ran along the street.The street lights were shining, causing rather sad-feeling. I walked around aimlessly.

A young father who held a child in his arms walked past me. I felt as if I saw my childhood from another space: happy and carefree.

But now … I don’t know whether it is because I have grown up or because dad is getting old. We differ in our ways of thinking. He always put his opinions of behavior on me. Whenever I do something wrong, he never admits(容许) it. We are just like two people coming from two different worlds. It feels like there is an iron door between us that can never be opened.

I wandered the streets, without a destination in mind. My heart was frozen on this hot summer night. As I walked on there were fewer and fewer people on the streets, until I had only the street lights to keep me company. When I finally reached the high-rise apartment block in which I lived, I saw that the light was still on.

I thought to myself: “Is father waiting for me, or is he still angry with me?”

In fact, it was nothing. Perhaps, dad was throwing away some of his old stamps. Perhaps he thought they were useless. I never had the courage to tell him that I liked collecting stamps.      

All the lights were off except father’s.

Dad was always like this. Maybe he didn’t know how to express himself. After shouting at me, he never showed any moments of regret. However, after an argument he has the habit of tucking me underneath the covers (掖被子) while I am sleeping.

This was how he always was.He has been a leader for so long that telling everyone else what to do has become his second nature.

The light was still on. “Am I wrong?” I whispered, maybe… With the key in hand, I was as nervous as I had ever been. At last, I decided to open the door. As soon as I opened the door tears ran down my face. I suddenly realized that the iron door that I had imagined between us did not exist at all. Love—it’s second to none!
