Not having a drivers license, no, not strange. I’m 24 and I don’t have one (though I am working on it, as I realize that some careers require one, and I don’t want to have to renew my permit again). And in many places, you simply don’t need to drive–the “drivers license as coming of age” thing applies mostly just to Americans.
Not having an ID at all, however, is weird. Not immature, per se, just strange. Can’t you get in trouble for not having ID if, say, the cops ask for it? And if I were to die in an accident and my body got horribly mangled, I’d want there to be some other way to identify me.
Not having a job…eh, it depends. If you’re willfully lazy and just plain don’t want to get off your ass, yeah, that’s pretty immature. If you haven’t had your first job by, oh, 25…well, I suppose there could be good reasons for that, but it does strike me as strange. (I myself didn’t have my first job until I was about 20, though I’d done a lot of volunteer work.) If you’re looking for work and just can’t find it in a shit economy, are in school, or are unable to work for whatever reason, those are all legitimate reasons not to have a job.
Not having a car, no. Cars are expensive, and, like I said before, are often unnecessary. I don’t have a car, but my boyfriend does. When I get my license, we’re going to share his (and I can easily bus to work…if I couldn’t I probably would have worked a lot harder on getting my license sooner).
Not having your own place…eh, not really. In this economy there are quite a few 20-somethings living with their folks, and again, cultural differences matter. I live with mine. I was going to find an apartment with my boyfriend, but when I told my folks this they just looked at me funny and said “why don’t you just live with us? It’ll be a lot cheaper.” Can’t argue with that! That being said, I don’t plan on doing this forever.
Not having sex, hell no. I have a friend who’s asexual (so, no sex drive whatsoever). He works a full-time job, has his own place, has his own car, all that other stuff. If you tried to suggest to him that electing not to sleep with anyone, ever, didn’t make you an adult, he’d laugh in your face. Even if you DO have a sex drive, there are perfectly legitimate reasons not to have sex.
