When I was a child, this happened to me when I was walking and playing in a small park, there was a drunk who came. He said what are the children doing here, I answered that I was playing but I didn't know that the person was drunk so he pushed me down after that he kicked me on that day I was still small, about ten years old, I couldn't possibly fight back so I went home and cried' that's what I experienced in my childhood, it was really sad.
Sad indeed that an adult would kick a child. Hopefully, you grew into a man and found that drunk and ended his life, although I presume not and the child-kicker is still out there.
