Dishonest me

I can't remember what I've done before, but I do remember i did the most dishonest thing.
I was a naughty child when I was ten, and I liked to play dodgeball very much. I used to play dodgeball with my classmates in elementary school. and we liked to have a cometition to see who can throw the ball farther. One day, we still played the ball just like before. Then, thing happened. I throw the ball too farther and it hit the window. The window was broken because of my ball, but I didn't confess that I did so. Though I felt guilty, I didn't tell anyone that I broke the window.
