The boys love playing marbles. Of course, B2 turns marbles into a bit of a rugby match by the time it's done -- he'll get fired up and/or feisty, and marbles go flying around the place. In fact, I told him a couple of times, "It's marbles, not rugby, Buddy." But for a brief, shining moment, the boys will peacefully play marbles, which is cute to watch. I offer a running commentary as we play. B1 pretends (of course) that the marbles are stars and/or planets, complains about "gravity wells" when a shot goes awry.
