You didn't ... But, uh, the Mr. Jotaro I know is pretty much all business. He never talked about personal stuff. In fact, think the longest conversation I ever had with him was about a freakin' rat.

[ And Josuke didn't feel like he could ask or initiate any kind of friendly interaction with the older Jotaro. Nothing felt important enough to discuss -- nothing that wasn't a dangerous stand user they had to take down or a mysterious occurrence they had to investigate. Pressing matters. Some people just don't look open to personal interaction, and Jotaro was one of them. Josuke didn't want to annoy him or bring up a conversation he doesn't want to have. He respects his older nephew a lot and cares about how Jotaro sees him. Even with the permission the older Jotaro had given him here on Lunatia, Josuke only satisfied trivial curiosities such as asking him about his favourite music or movies. He definitely didn't want to risk their relationship by asking him about something painful. ]

My old man told me, though -- And I actually met some of them. Mr. Avdol, Mr. Polnareff and Kakyoin, right?
