The Mathematics of Betty’s Walking

Betty and I are walking down the sidewalk of a rather busy street when a car screeches to a halt in the middle of the road and a kid jumps out and asks: “Can I pet your dog sir?” And Betty makes yet another friend. I don’t get it. What is this mysterious attractive force that Betty possesses? I don’t recall studying any such thing in the physics classes I took. Is it some sort of undiscovered force? The Betty force? Do they give Nobel Prizes to dogs?
As Betty and I were strolling past a house occupied by some of her friends, I heard a little girl’s voice coming from the back of the backyard: “Look! Oh my goodness! It’s Betty!!” Before I had a chance to extend the leash, the little girl zoomed across the yard and smothered Betty with love. The dogs who live in the house were clearly not happy with this event, but what could I do? Betty is a magnetar.
