One day, a single woman walked through a dark tunnel with sad eyes. She cried so badly that every tear that dropped damaging the crops. A little kid follows her, and wonders what happened to the crops. Why is it all turning black? Then he realizes that the tears were the cause. The kid slowly approached that woman. The woman ignores the kid and keeps crying without knowing the damage that she caused. The kid came up with an idea. He makes a little container and connects it to a little pipe that end up in a gallon. Then the kid approached the woman again, and that woman felt confused. The kid adjusts the container, so it can fit in her eyes. The tool works properly, so every time that woman cries, the tears will end up in a gallon, so it won't damage the crops.
The woman thanked the kid, and she can cry quietly without damaging any crops.
