"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 feelings. I wandered 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 care-free.
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 and codes of behavior on me. Whenever he do something
wrong, he never admits 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. I can't stand his outrageous (蛮
横的)words:"I can't throw you away, let alone these old papers!"
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 mercy or any moment of regret. After an argument he has the habit of creeping up in my sleep
and then tucking (帮助盖被子) 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. "Am I wrong?" I whispered, maybe... With the key in hand, I was as nervous as I
had never 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's second to
none.
