Embarrassing moment: Why does this always happen?

I was in my school, at lunch time, at the football pitch, we were playing football and I was looking forward to scoring a goal. We were keeping up with the enemy, who always is the winner of the game. I was taking care of our goal and in charge of the attack of the team. There were 2 minutes left for the bell to ring, it was my last chance to score the goal and win the game, so I got the ball and made up a way to score the goal, I saw a space between the two other players, I passed between them and I was free to score a goal, but I fell down and the impact took off my shoes, I was so close to the goal, then everybody started to laugh. I was alone and free to score but instead I fell down. Everybody got out of the pitch laughing at me and I didn’t score a goal. I felt so strange; I wanted to be on the other side of the world.
