Most awful thing you ever witnessed...(Possible triggers inside)
When I was 14 I was outside riding bikes with several friends of mine. We turned onto one friends street and he saw his dad pulling out of the driveway. He rode up to catch up with him. His dad didn't see him and was drunk. He swerved and knocked my friend off his bike. He somehow ended up under the truck. He died during surgery. I have no recollection after turning onto the street until the next day. Everything I know is from being told after the fact. It was awful. I remember everything up until turning onto the street.
My second story... A friend was leaving a small gathering. He put his son in his infant seat and strapped him in but didn't strap the seat into the car. He was only going a few blocks and not leaving the neighborhood. Some drunk came flying through the neighbohood and tboned him. He flipped the car and the seat went flying. Luckily the baby survived.
Last one for now. Driving down the highway I saw a truck with a dog chained in the back.. The dog took a leap out of the truck as the truck took off and the dog was decapitated.
