Atticus’ statement “ jem’s definitions are very nearly accurate sometimes” (28) is meant to create what tone?

The statement on the part of Atticus that "Jem's definitions are very nearly accurate sometimes" is meant to set a playful tone because earlier Jem had said that entailment meant getting your tail stuck in a crack.

He might have a farm, but he does not have to right to sell it a large part of it and dispose of the money as he wishes.  Therefore Walter and his father are poor, and kind of "stuck in a crack" when it comes to affording to take a lunch to school like Miss Caroline expects.
