There but for the grace of God go I...
When I was about her age, my friends and I did stupid things; fire and gasoline, fire and starting fluid, whatnot. Experienced the awesome power of fuel without paying the ultimate price doing so. Some kids are lucky. In her case, it sounded like not recklessness but simple absentmindedness. The fire was going out so without thinking, she reached for the can of gasoline to start it back up.
Her actions also injured and burned three other people, forever scarred.
I wonder if she wound up with a staph infection at the hospital being there so long.
