chimney fire

Well about a week ago my pastor was at home and his son said dad something is wrong with the woodburner and he opened it and a bunch of smoke came out and my pastor said son your just opening it to fast and he went over there and opened it a little bit and still a bunch of smoke came out and he said son we have a problem and he listened quietly and heard a sound like a locamotive and he said son go google up chimney fires. And so he went up stairs and one of his other sons that was younger followed him and my pastor looked and there was a picture and his younger son looked over his shoulder and had his jaws dropped and my pastor said son you dont need to see this so my pastor took a old blanket and stuffed it in the chimney and said to his older son son watch that make sure it dont catch fire and he went outside and there was black flying out of the chimney and there was snow on the roof and around the chimney it was all black and he went back down stairs and the blanket was on fire and he grabbed the blanket and threw it and bured some of his skin and they put out the fire
