What was the first event that disproved your childhood belief that the world is a safe place?

My dad and I were sitting at home on a Saturday afternoon and we heard this huge crash, then a minute latter we hear sirens right down the street, then more sirens. My dad worked on an ambulance for awhile in the past, so he decided to go see if he could somehow help since we kept hearing more sirens come. I came along because I was still a bit too young to leave unattended, but old enough to know not to get in the way.

At the bottom of my street, We saw 2 fire trucks, 5 police cars, and 2 ambulances. A car was upside down and wrapped around a tree. The car held 4 teenagers inside of it and multiple firemen were trying to cut into it with the jaws of life. While I watched, a medical helicopter flew in and landed in a field to the side of the road. I was close enough to feel the wind from its blades as it landed.

I watched as two of the teens were pulled out and assessed, then strapped to gurneys and put into the ambulances. These two teens were both awake and I kept my distance cause I was really scared that I was going to see blood. I had never seen a bad injury before and my imagination made me feel a little nauseous.

When I turned my attention back to the wreckage, I saw them finally make it through the driver's door and quickly pull the body onto a backboard and with a team of officers, they ran the body to the helicopter and the helicopter took off.

About this time my dad returned to me, and told me that the hard work was done. I watched as a single fireman took the jaws of life and began cutting into the passenger door. I asked my dad what he meant, there was still one more person in there. My dad shook his head and told me the officers can take their time now, the teenager in the passenger seat didn't make it.

That night on the news we watched a news report of the aftermath. It was determined that the teens were speeding and trying to jump the hill that was on that street, but lost control.

A few months later, the entire street was rezoned and moved about 100 feet over so that the road was now a gentle slope, and had a less sharp turn.
