Alright, I like Robinson, I didn't even realize his other stories, but this one is a little fuzzy.
It reminds me of this time when I was 12 at A friends house after school. One kid decided to see if a lighter would ignite the curtains! They ignited all right. We got the fire out, cut the charred remains from the white curtains and blamed it on the cat. I honestly don't remember if that kid ever came out with it.
