When I was a kid my grandma used to take me for a drive on our golf cart (grandparents had a large farm and sometimes it was just more convenient to use that to get around the place) to visit the elderly lady up the road, sometimes 3 or 4 times a week. She was super nice and would always give me candy when I came to see her. Good stuff, like snickers and Reese's cups, so I was a huge fan. We'll call her Mrs. Violet.

One day when I was roughly 5, we went to visit and my grandma had locked the brake and the two were talking. I don't remember the specifics, but for some reason I crawled over my grandma's lap to reach for something and I accidentally hit the gas. (It was one of those carts where if you push the gas hard enough, the brake unlocks)

I floored into Mrs. Violet and her head smacked against the pavement. She had a seizure and I just remember blood streaming out of her nose and mouth, and the ambulance putting her in a neck brace when they finally came. She couldn't speak or move. I remember my grandma gripping my arm while we waited for the EMTs.

I never saw her again after that and to be honest, I'm not sure if she ever fully recovered from it. No one would tell me, and never did. My grandma hated when I brought it up. No one knows about it. I still feel guilty about it. Sometimes I wonder if I killed her but I'm too afraid to dig deeper to actually find out.
