Boruto literally spewed a few rounds of nonsense into the face of a kid, who can be defined as a local prince - really "mature", indeed.

Note that this is *post-Academy genin* Boruto, not *Academy-start* like in the anime.

I can understand Naruto (an orphan) acting this way - but there's literally no way that a son of Hinata (a former clan heiress) would be allowed to be such a brat at such a responsible (in-universe) age.

Strict mom or not (probably YES), she's still clearly personally VERY familiar with internal politics and etiquette - and definitely taught her children it as well.

Boruto has no logical reasons to behave like Naruto of his age - regardless of his own personality quirks.

He's the Hokage's son - so he has to *represent* his position as well.

If anything, the daimiyo's kid wasn't even half as bratty as Boruto - and he also clearly wanted to befriend him first, which is an interesting quirk there.
