i see this one differently. he just looks used to things, this routine, and slightly indulgent of whomever he's looking at. i really get the impression he's going to take that cup that's being offered any second. also, sometimes i think he's about to laugh. lol it's just such a knowing look, like wry, cynical laughter is about to be shared.
probably just me, but i see it every time i look at this card.
