quote from apostate man....
When I was eight or nine (BTW, these are all true, to the best of my memory)my stepdad(x now) and his best friend were standing out side the house. It was getting dark. The friends name was Denny and was a religious man(not a JW, I said religious). My stepdad, I believe had many demons in him. Long story short, my mother screamed for me to get in the house, I looked back outside and there was a fireball looming above Dennys van. Never touched the van. This lasted for about 30 seconds.
A year later. We had a bad storm come in. Tornadoes, lightning, thunder, rain and wind. Middle of the day lightning struck the dining room window, did not break it, and a ball of whatever actually skid across the tile in the kitchen and melted it. There was a 4-7 foot melted path left behind. I was in the basement when this happened but did see the floor all scarred up.
