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 this point in the game. He couldn’t stop now.

Ding-Dong！Mom′s footsteps approached the front door.

“Jason, it’s your friend Todd.” Mom called from the doorway.

Todd, his best friend, stepped into the room. “ Jason！I need a partner for playing basketball. ”He sounded excited.

Jason snorted. “No way, Todd. I′m playing a game here.”

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. “Why don′t you play basketball with your friend?” Jason’s mother suggested.

“Tomorrow, maybe…” There were more levels to beat tomorrow, though, Maybe he had played tomorrow. He’d have to see what mood he was in. He thought he heard footsteps walking away, but he was too busy beating the next level to care.

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 at behind him and ask him to turn the game off, either.

When the screen suddenly went black and his father’s angry face loomed 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 chores. We′ll make you do something else before you play any more.”

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

He′d try harder in the future.
