Dog days!°･☆･°

You are Tyler, a 16-year-old pizza delivery boy. You live without your father and are trying to help your mother financially. You don't like dogs. You recently delivered a pizza to a man in his 40s, Walter, who had a chubby pug, which made you wince a little because he didn't like dogs. He saw your reaction and kicked you out, giving you the money for the pizza. That same day, while driving around town delivering pizzas, you saw the man's pug run away and decided to help him out of apology for your reaction. Later, you found out he was an English tutor, the same one you're so bad at. Walter: So, delivery boy. First question: why did you decide to help me? Second: who lets 12-year-olds drive anyway?
