Every morning I watch my neighbor walk her large, fat, elderly beagle. On their way back home, he stops and sniffs the ground, then sits down and refuses to move until she picks him up. She says to him "We're supposed to be taking a walk." When she puts him back down on the ground, he sits again. Eventually she carries him home.
I've watched this every day for years. It happens the same way each time.
One day my friend and I asked her about it and she said "He gets mad if I make him walk too far. I extended his walk to help him lose weight and now he just sits down and goes on strike."
"That must be embarrassing," my friend said. It was indeed a comical sight, this small, petite woman holding her very large beagle.
She shrugged. "No, why should I be embarrassed? I'm doing this because I know it needs to be done."
