Iremember squatting in the road drawing a picture in the dust, a picture which joey gleefully erased with one sweep of his dirty foot. i remember fishing for minnows in a muddy creek and watching sadly as they eluded my cupped hands, while joey laughed uproariously.

how does joey's behavior contribute to the mood of the excerpt?

his mischievous actions add to lizabeth's worries.
his angry acts make lizabeth question her loyalties.
his cheerful outlook lizabeth see things differently.
his childish thoughtlessness contrasts with lizabeth's emotions.
