Remember the Old Testament story of the soldiers lapping up water from the stream? The right way -- on bent knee and scooping up water as they looked about, wary of the enemy's approach. The wrong way -- on both knees, bent over, lapping up water from the stream like the dogs they were. Well, we know who were chosen.
My point is that the Asian bro has the handle of his book bag draped over one shoulder, wherein a passerby, intent on robbery, could grab the bag in an instant, and make off with valuable booty.
The Hispanic hombre, on the other hand, has the bag crossed over his head, making a would-be thief not overly willing to mess with less than easy pickings. Spiritual food, as harbored by Jehovah's Witnesses, is a recognized treasure trove, valuable beyond gems and gold and silver. I know, because I used to produce it at Brooklyn Bethel.
I always hated when the WT conductor asked the meaning behind the illustrations and the spiritual as well as practical lessons learned.
