As John stood opposite Bob, they both looked at the tiny piece of chocolate sitting peacefully sitting among the crumbs on the plate. They had divided the other chocolates fairly. But this was the last chocolate, and neither of them were going to give it up to the other. "I'll get the chocolate, you get the crumbs", Bob declared. "No way, I get the chocolate!", shouted John.
"No mine!" exclaimed Bob.
"Hey, I was the one who brought these."
"Exactly, guest gets the last one."
And they both grabbed it. Sadly, during the scramble, the chocolate flew out the window.
