It’s where a person goes when they’re lost that reveals their true beliefs, and what holds them together when life gets rough.
There’s nothing left for him back home, even if he could remember where to go. So he goes on an adventure to learn more than he ever could at home (which was surprisingly easy). Even so, it isn’t difficult to imagine those extra words that his parents would insert into his newfound independence, perhaps not intentionally trying to hold him back but more out of worry and love. He still prefers to learn lessons the hard way, though, instead of the hovering shelter his parents provide. But he’ll still take any advice he can get, and hopefully he’ll remember when it really counts.
Hopefully, he’ll remember that he’s still a child as long as there’s someone looking after him, and that once in a while, it’s okay to let other people take care of him.
