What does the teachers' attitude toward Finny suggest about his personality?

Even though Finny somewhat lives in a world of his own, he is charismatic and can talk his way out of any situation. He is one of those people who do not live by the rules; he wants to make his own rules. The teachers' attitude is that they treat him more like a mischievous child that a blatant rebel and rulebreaker.

Oops - mischievous child THAN a blatant. . .

Some days it is hard to spell! :)
