“BANG” the door caused a reverberation．“Never set foot in this house again!” shouted Father．With tears welling (涌出) up in my eyes，I rushed out of the house and ran along the street．

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 harmonious.

But now I don’t know whether it is because I have grown up or because Dad is getting old．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 street，without a destination in my mind．My heart was frozen on this hot summer night．As I walked on there were fewer and fewer people in the streets，until I had only streets 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 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 1ike this．Maybe he didn’t know how to express himself．After shouting at me，he never showed any mercy or regret. After an argument he will creep(蹑手蹑脚)up in my sleep and then tuck me underneath the covers.

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. 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 cheeks．I suddenly realized that the iron door that I had imagined between us did not exist at all. Love－it is second to none．
