Crack

I am standing in the doorway. My aunt and my mother are on the street and they are roller skating. My aunt tries to do a move where she swings my mother under her legs and up - like a jitterbug, but it goes awry. My mother faints as she comes up and therefore hits the pavement with the full weight of her body, head first. I hear a terrible "crack" - is it her head or her neck? I scream and call 911. The phone rings and rings to infinity.
