The story is about the emotional walls people often build between themselves to restrict real communication of feelings. It's excerpted from Show Time (see my books). It also alludes to the cultural walls we build for the opposite effect: to enhance communication of feelings.

Excerpt:  So Bobby dug deeper, entrenched behind the wall he'd built years ago, one or two bricks at a time, sometimes whole rows, an impenetrable wall with the best and strongest mortar, all the way around him full circle, tall as the moon, thick as the earth. But the wall was coming down now, brick by crumbling brick, and like the little Dutch boy, Bobby sometimes felt forced to stick his thumb in a hole, sometimes a fist or two, and occasionally he had to roll up all of his energy into one gigantic ball of strength and trowel over a break like so much cement.
