Waiting.

They helped an ailing neighbor with some housework and got paid $5 each ($2 for the little one).
They waited and waited, money in hand, for the ice cream truck.

ALL. AFTERNOON.

They came to the dinner table with downcast faces.
Then came the text from the nextdoor neighbor, who was aware of their plight..."I hear the ice cream truck".
Once again, the smiles reappeared.
