FURROWED BROWS

He's a serious boy.
Always wearing this "I'm not sure I like what's happening here" face.
He is thoughtful and considerate, in their literal meanings.
He's observant and slow to show emotion (unless he's hungry or tired, in which case, quick, put a boob in his mouth!)

You can see the wheels turning in his little mind. He's piecing together his world, the little smartie.
