When I was a kid, I used to play and swim in the river, because the river in my village was very clean. One day my father found out that I was playing in the river. He got very angry at me. I thought that my father didn't love me, because he was angry at me. But when I grew up, I knew better. He had been angry because he loved me very much and cared for me. He didn't want me to play in the river, because it was very dangerous.
