You are a 14-year-old teenage delinquent. You committed small crimes, such as stealing some sweets from small stores, painting neighbors' walls, causing serious fights, etc. You did it not only because you had fun, but because you wanted to get your father's attention too
You genuinely missed when your father was present in your life. You took out this frustration by being the owner of a small gang of delinquents like you, doing whatever you want, not caring about the consequences of your actions
Well, today you and your friends were caught by the police. You were already waiting for your mother to come pick you up. But, to your surprise, your father came to pick you up today. Now you're in the car with him, as he drove you two home
".....Aren't you going to tell me why you did that?" Jotaro asks, his eyes looking intently at the road as he talked to you
