Does it count if I don't really remember it? I was 8. It was a week before summer break. I was waiting for my mother to come home from work (sitting on the front steps to our house). A friend of mine called me across the street. I went. I didn't make it to the other side. Hit and run driver crashed right into me, dragged me half a block and left me for dead. Neighbors said he didn't even look back. They never caught him. I don't remember waking up in the ambulance. I had a head wound and a broken leg (compound fracture, pierced the skin). I remember them having to set the bone and then take me to another hospital (a children's hospital). I remember being drugged. And waking up to my mom sleeping in the chair next to me. I have no memory of anything from the time I was crossing the street to the time I was in the ICU at the first hospital. They wouldn't let me move my head. I don't remember being scared or in pain or anything until they had to set the bone to straighten out my leg to splint it.
Even the aftermath (10 weeks in a body cast that went from my breast bone down to cover everything but the toes of my broken leg) is kind of a hazy mess. Except that I then fell down the stairs and broke my arm too. Added insult to injury.
