"BANG !" the door caused a reverberation . 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 walked 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 puts his opinions of behavior on me. Whenever I do something wrong, he never turns a blind eye to 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 walked aimlessly on the streets, without an exact place 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 be with me. When I finally reached the high-rise apartment block in which I lived. I saw that all the lights were off except the father's. I thought to myself: "Is father waiting for me, or is he still angry with me?" "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 cheeks. I suddenly realized that there was no iron door between us at all. Love - it's second to none. What conclusion can you come to after reading the passage?
The father treats his son in an unfair way. The father is actually kind to his son. The father is neither kind nor cruel to his son. The father is always finding fault with his son.
