My sister had left a sandwich in the fridge with her name on it, clearly meant for her. I knew it was her lunch, but I couldn’t resist the temptation. I was hungry, and the sandwich was just sitting there, calling to me. I debated for a moment, but in the end, I decided to eat it anyway.

As I opened the sandwich, I expected something typical—maybe turkey and cheese or peanut butter and jelly. But to my surprise, there were only two plain pieces of bread. I stared at it for a moment, confused. Had she forgotten to put anything inside, or was there something I was missing?
