He bought that girl a car and then sold her out to his buddy and then sold her for cash. He’s a heartless piece of trash.
She bought her brother a phone and then sold him to the school bully and then sold him to a guy who gave her $20. She’s a total loser.
He bought that friend a pizza and then sold him to the restaurant and then sold him to a guy who paid $5. He’s the worst.
