How Is This Possible?

Holy shit, read this: After Drinking Gasoline, Man Lights Cigarette and Bursts into Flames

How do you "unknowingly" go outside for a cigarette? Was he that stupid, or is it just bad writing?

Yes, this man died, so I shouldn't be making fun of him, but this is fucking insane. Can you imagine someone you love dying like this? What would be the stronger reaction, "oh my god, they're gone" or "oh my god, I had no idea they were that stupid."
