When I eat a sandwich, I have to make sure that I have 10 crust pieces left so each dog gets two.....It's not really that hard, for those of you who are scratching your heads right now. Imagine a sandwich cut in half across the equator. Each piece has two sides and a bottom and each side and bottom have two pieces....that makes 12. So I have to eat two (any two) pieces and then there are 10 left. I yell "Sandwich time" and they all come skidding to a sit within reach of me. Then they eat like ladies and gentlemen.....
