Ding-Dong!

“Jason, honey? Can you answer the door?”

"I am busy, mom!" Jason shouted back at his mother. He had spent three hours so far working to his point in the game. He couldn’t stop now.

Ding-Dong! Jason’s mother came to the front door.

"Jason, it’s your friend, Todd,” Mum called out. Todd, his best friend, stepped into the room. "Jason! I need a friend for playing basketball." He sounded excited.

Jason said angrily, “No way, Todd. I’m playing a game here.” Todd shook his head, “you can play later, let’s go.” Jason gave his friend a dirty look, and his character in the game almost got killed while he looked away. “I almost died because of you!” Todd looked at Jason's mother. Jason's mother looked back at him. They both looked at Jason. But he just played his game.

An hour later, Jason's father came home. It was dinner time after his father washed up and sat down. Jason didn't even hear his name being called to the table. He didn't hear his father walk up

behind him and ask him to turn the game off, either. When the screen suddenly went black and his father's angry face appeared in front of him, Jason finally heard. "No more game for a month." Jason's father shouted at him. "You don't play basketball, you don't come to dinner, and you don't do your housework. We'll make sure everything else gets done before you play any more.”

Jason nodded slowly. He knew better than to quarrel with his father, and when he thought about it, he had been playing quite a bit. It was fun, but he was letting down (使失望) his friends, his family, and himself by playing too much.

He'd try harder in the future.
