Several years ago, I read about a New York City executive who was moving from appointment to appointment all day. He didn't have time to stop for lunch, so he purchased a sandwich from one of the coin operated vending machines. He put his sandwich on a table and went to purchase a soda from another machine.
When he came back to his seat there was a bag lady - one of those people who carry all their earthly possessions in a big bag - sitting there eating his sandwich. He was incensed - furious. He decided to sit down opposite her and glare. Evidently the woman felt uneasy because she handed him half of the sandwich. This made him even angrier.
The woman finished her part of the sandwich, picked up her bag and left. As she walked away he saw his sandwich sitting on a table untouched.
Sometimes things are not what they appear to be. That's one of the reasons we need to be kinder, gentler, and more merciful.
