Dan Howell and the Boy from the Edge of Town

"He thought what he was doing was weird, but he would never have called it stalking, being only 8 years old he had never heard of such a thing. He was only there to see how the boy did, well that, it was so cool. As Dan watched, the boy picked up a pebble which instantly started changing colour. Dan stared for a couple of seconds, before screwing up his courage and stumbling out of the bush."
