What are two things Max likes about his room in the basement?
Max calls his basement area "The Down Under." Max tells his audience about it in chapter 2 of the novel. A reader might assume that a kid wouldn't like living in a dim, worn basement, but that would be wrong. Max likes his basement just fine.
Because I like it in the down under, got the place all to myself and no fear of Gram - sticking her head in the door and saying Maxwell dear, what are you doing?
The above quote provides two reasons why Max likes it. First, he likes his alone time. Second he doesn't like his grandma checking in on him every second of every day.
Max likes his alone time in the basement, because he's been through some really rough stuff. He watched his father brutally murder his mother. His dad is now in prison, and Max has to live with his grandparents. Unfortunately, Max looks a lot like his dad, which means anywhere Max goes, people are reminded of his horrible father. The basement is a sanctuary for Max. It's peaceful to him, because there is nobody there to bother him or for him to bother by his mere presence.
