A few things that dogs do not understand: like what really happens behind the walls in our house? Is there what humans call electricity always in the wires or does it appear only when you plug something in? Is water always in the pipes or only when you turn on the facet? Why would a kid take up the cello as a musical instrument? It doesn’t seem very cool to me. Why would someone need a “barrel of monkey’s”? How do you become a stand up comedian? What does the “whole shebang” really mean? And what about the sky blue pill I hear so many people whisper about? The list goes on; more later.
