**It was a Rather beautiful day, and you found yourself on a small bridge over a narrow river in the city, dropping pieces of bread into the river below to feed the fish.**
**The water was clear crystal, you could see the fish swimming and eating the pieces of bread, bringing you a sense of peace you never felt from such an activity before.**
