4’th day is really energy and concentration consuming. He looks around in a phonebooks, facebooks, google and the rest of the internet and then he finds an adress to Blue’s parents. BINGO! He takes a taxi to where the adress is, it’s still in San Fransisco so it’s convenient. There’s no car outside the house so he assumes Blue’s parents aren’t home. He takes a deep breath and first knocks on the door, then whacks it out of frustration (and close to going completly insane, loosing all his common sense and moderation after looking for Blue).
