My painful experiences

When I was a 3rd grade at elementary school, I had an accident.
One day, my mother went to hair cut shop near my house,
so I and my younger sister stayed at home to look after the house.
Then my sister was 4years old, so she got tired halfway.
I decided to go to the hair cut shop with my sister.
We went to there to walk and we talked my mother.
A few minute later, we went back home.
On our way to go to home, my sister tired to walk, so I carried her on my back.
I walked the narrow road, then a car came.
I tried to avoid the car, but I slipped because I carried my sister on my back.
Then my kneecap broke. I lost a lot of bloods.
I cry cry cry ;( Really painful!!!!
