Oh yeah I would be nervous too
I actually just crossed state lines without my parents for the first time 2 days ago (though in late 2023 I actually left the country without them first lmao)
the thought of my little brother doing that would scare me too
He legit got to go on a 3 day adventure with a youth group a couple months ago
I never did anything like that till I was quite a few years older than him
