One day, P'Neena Margalit left her job as a software developer to buy some new boots. She wore four boots, one for each foot. When she walked into the cobbler's, the man at the leather-working bench looked at her in a queer way. "Where have you wandered in from?" he asked her. "The street," she replied. Curiously, though, the cobbler appeared not to understand her. He waled over to her, patted her on the head, and told her to hold on a moment as he disappeared into the back room. P'Neena stood waiting patiently while she puzzled over the interaction she had just had. "What an odd fellow," she thought to herself. Before she could come to a definite conclusion, though, the man returned from the back room with a bowl of milk.
