He got home from work at 10 p.m. His wife was still at work. A note was on the refrigerator. It said, "I was home for lunch. There are leftovers in the fridge. Just heat and eat. Enjoy!" What an angel, he thought. She was always thinking of him. He put the leftovers in the microwave. He turned it on. The phone rang. He talked to the caller briefly. He hung up. He got on his computer. He searched for some files. His wife came home. He found the files. He attached them to an email and sent it to the caller. He went into the kitchen. He opened the microwave. It was empty. He marched into the living room. His wife was watching TV while chowing down on the leftovers. He said, "Hello! I thought that was for me." She said, "I'm starving! Thanks for heating it for me."
