Brothers

Maybe this should've been obvious, but Michael & Jack are very close as brothers. Ex. 1: Jack sometimes prefers a favorite kid's spoon, but it's often gone missing, creating the typical table banter: "Spoon."

"I don't know where your spoon is. Say that in a nice way, please."

"Spoon, please, Mama."

"Spoon!"

More often that not, Michael will jump down, canvass the area, and return triumphantly with Jack's spoon. I think Michael does good deeds mostly to impress us, but it dawned on me that Jack actually goes into his utensil mantra, knowing full well that older brother will fetch it for him.
We noticed some time ago that Michael often signs his pictures as a twosome, "Michael Jack."

M & J on both sides of a birthday cake. Very sweet.
