They said "I'll never feel like an adult". Emphasis on I'LL and FEEL. Not NOBODY, or EVERYONE, nor IS or BE. I'LL FEEL. Completely personal question, to a completely subjective answer -- yet you came here and contort their response in some misguided attempt to be upset with someone on the Internet so you can feel something.
Come on.
You (and other posters) are the ones being all touchy. I've got 14 downvotes for pointing out the paraplegic/housewife angle.
HN is not too friendly toward basic philosophical inquiries!
Are you sure you feel like an adult, or are you talking about feeling like a man?
This isn't a meaningless distinction, and it also doesn't need to be offensive. Alas, it seems if I want to have public philosophical discussions I should go back to 300 BC.
I'm a guy. For some reason, in my mind, adulthood for guys is defined as having a really great beard.
And for some reason, I can't grow a beard. I get a tiny little patch under my chin, and that's about it.
Because of this, sometimes I feel like I'll never be an adult.
The discussion sounds a lot like 'when do you become a man' than it does 'when do you become an adult.'
For instance, most women throughout history were financially dependent on their husband. They would not make independent decisions. They were not solely responsible.
Did that mean they weren't adults?
The 20-30% of women who still become stay at home moms... they can't grow a beard... they are dependent on their husband or parents for money...
