It's
It’s the way he smiles after he’s made a joke
It’s the way his eyes light up when he’s talking about something he’s interested in.
It’s the face he makes when he knows he said something wrong.
Its the way he can’t hold in his laugh after someone makes a joke.
It’s the way he acts like a chid, even though he’s an adult.
It’s the face he makes when I make fun of him.
It’s just him.
