My sister broke my arm.

This isn't going to be the usual long story but it is pretty funny. One day my two sisters and I were playing on this one big chair downstairs. I was probably seven and my eldest sister was twelve. We would take the back of the chair and then we push up on it and flip over the chair, now landing on the seat of the chair. Well it was my turn to hop over so I did and I stayed on the seat for a little bit with my arms behind me keeping me sitting up right. So all of a sudden my big sister hops over the chair and lands right on my arm. Keep in mind the way I was positioned. and she snapped my arm. So now when I tell the story all I have to say is " My sister broke my arm by sitting on me."
