oooh i got one!
when i was younger, my dad left me and my sisters in his truck to run in a store and get something (irrespondsible of him i know) and me and my sister were fighting or somehting, and i kicked it out of park cause the stick thingy was in the middle, you know what i mean. anyways, we rolled backwards and hit a parked transport. beyond that transport was a busy highway. i could have gotten killed.
haha okay, nothing big i know. but i was so scared right then i was crying as we rolled backwards.
