I look at these boys, brothers no doubt, and think of Cain and Abel. The one with a slight smile, the other unemotional. I also think of the two brothers in East of Eden.
I have no information about these boys. We bring to them what we want.
I find it interesting that their hair parts in different directions. Perhaps they're twins and the mother parted their hair differently so she could tell them apart. However, the one on the left looks slightly younger.
