Hahahaha I loved the story. It reminds me a lot of an experience that I had to live as a child.

Answering your questions I consider the following order:

1: Benny was tired because he had a lot of activity throughout the day.

2: I wanted to stay for obviously, play with your video game console

3: Because he thought there were too many of them and when he finished them he was not going to have enough time to play

4: So that it arrived directly at the bed! very clever haha

5: Well, he missed not having gone to school because the tasks were so tedious, to the point of missing his friends from school. In addition, he has not been able to play ... Very fatal things for a child. I think if he learned it, although he will look for new excuses for the future
