I'm sure he'd be all like:
"Sasuke my dad's the HOKAGE, the greatest in the village, and i'm gonna be HOKAGE next-ttebayo."
Not really.
Boruto doesn't want to become hokage.
Boruto hasn't really shown to give his teachers trouble, just his father.
Boruto hasn't really shown any insensitivity to girls' feelings.
Didn't he interrupt Shino?
He did for Sarada until she started talking about his mom.
I think that was the class in general that interrupted Shino (not solely Boruto). You can show me the scan again though if you'd like.
That wasn't insensitivity towards Sarada. That was just disagreeing about what should be done with the bagged lunch. The fact that Boruto actually changed his mind and handed over the bag after considering Sarada's point actually shows sensitivity rather than insensitivity.
