One night there was a woman at the airport who had to wait for several hours before catching her next flight. While she waited she bought a book and a pack of biscuits to spend the time. She looked for a place to sit and waited. She was deep into her book, when suddenly she realized that there was a young man sitting next to her who was stretching his hand, with no concern whatsoever, and grabbing the pack of cookies lying between them. He started to eat them one by one.
