yes it's truely amazing what these suckers can eat. Think of your snakes for a second...if your snakes are with you from babies, up until they're full grown adults, they know your scent, they know who you are. My best guess would be that this kid has been around this snake perhaps his entire (young) life, and the snake has been around humans its whole life too. The snake knows who he is, and doesn't see him as prey. Although it would make a very easy meal of the kid.
