Button, Button

A young bog named Johnny finds out that his grandma needs surgery. He begs her to tell him if there is any way for him to make money for the surgery. She says no. A couple of hours later a box arrives at the front door with a letter. The letter explains that if you push this button then you get money. Was it that simple though? No. You push this button then someone in the world dies. All you know is that you don't know that person. The young boy wants to press the button because he wants the money to get his grandma's surgery and maybe even get some things of his own. The grandma yells at him and explains why he will not press it. He does. In the end, the person who dies was his grandma. He never really understood and listened to his grandma so he never really knew her.
