[ Okay, sure, we're gonna teach this kid how to begin a life of crime. ]

Think of it this way. Suppose you want to rob a house, but the only ways in are the front door and the chimney.

If you seem suspicious, you gotta take the chimney, which means climbing all the way up the house and crawling down a dirty hole into a fireplace, all without anyone hearing you. If you seem nice, you can just talk them into letting you walk in through the front door.
