You can just see Grant thinking, "These **** young whippersnappers..." LOL
Scout does the exact same thing Stannis is doing there when she wants someone to play with her. Except she's a lot larger and louder. Its super awkward when she's trying to get her BC boyfriend to play.
Grant is like "Ohmehgosh, ladeh. Where did you find this thing? Take it back! Go way, dog, go! I'mma look this way, and you go thatta way. Go. You're not going. Go. You're not going. Go. You're not going." ROFL!
