<human>: I'll try to keep mine short. My father used to be a volunteer firefighter whenever I was very young. Then one day he suddenly quit and I had no idea why since he loved the job and one day wanted to become a full time firefighter. I questioned about it a lot and he would always give some arbitrary reason. Finally, my mom sat down one day and told me the gruesome story. My father had gone into a pretty raging trailor fire to try and save a pair of twin sisters still caught inside. He finally found them, but at that point they were just two charred bodies holding each other for dear life. I have never experienced anything close to that and honestly it kind of messed with my 8 year old mind a bit. He still has no idea i know about it and i make a point to never bring it up. Anyone else have similar experiences with their parents? I'm sure there are some really intense stories floating out there in reddit.

Can you give me the gist of the text in a nutshell?
<bot>: found out at a young age why my father stopped volunteering at the fire station and it was pretty gruesome. Anyone else want to share?
