When I was young, I liked to play jump rubber band. One day, while I was playing jump rubber.
There is a girl who don"t know. She ran into my back was badly.
As a result I fell backwards struck down to the ground. The nosebleed gushed out.
I remember crying.
But the anger made me conscious control at all. Hit her back by mistake.
Now I feel guilty about the incident in the past to apologize to her.
