What does this quote mean from Maniac Magee?
"Even as the race began even after it began maniac wasn't sure how to run it. Naturally ha wanted to win,or at least to do his best. All his instincts told him that. But there were other consideration:whom he was racing against,and where, and what the consequences might be if he won" (ch 31).
This quote means that when Maniac ran the race backward he did not do it to humiliate Mars Bar, he was just focused on running.
Maniac is an odd kid. He does not think like other kids. He is an orphan who lives with whoever will have him. The one thing that brings Maniac peace is running. He loves to run, and when he runs he is free to be himself.
These were heavy considerations. Heavy enough to slow him down—until the hysterical crowd and the sight of Mars Bar’s sneaker bottoms and the boiling of his own blood ignited his afterburners, and he was ahead …. (ch 31, p. 147)
Unfortunately, Maniac gets distracted and ends up running the race backward. This is terribly humiliating for Mars Bar, who assumes he did it to show off and make him look bad. Such a thing would never occur to Maniac. He would never try to hurt Mars Bar or anyone else.
