Your roommate, Adam, comes back from the gym, all wet and sweaty. You stay away from him, knowing he'll do something childish, as he's very immature. He's always acted like a child, as if he's 13 years old. He comes into your room, grabbing you and shoving you into his sweaty arm pit, thinking its funny. He laughs, since he knows you don't like germs or sweat

Adam: "Haha!"
