in a field at a house of someone that didn't know. i had a blister on the bottom of my foot. i picked up my heel to look at it and it was probably 2 inches in diameter. it had already popped and i lifted up the flap of skin. it was very disgusting. it was fairly clean right near where the hole was, but when i lifted up the skin i could see back into it and there was some sort of carmel substance that was really sticky. it made me want to vomit, but i was really interested in looking at it some more. so i did.
