I observe the way most adults look and behave, and I have no idea why I'd want to "mature," unless I excelled or was a paragon at something. It seems like most of them lead miserable lives they were financially coerced into living. They didn't have the right genetics and/or upbringing to do something interesting for a living, so they're relegated to the mercy of our neo-fuedal lords or some soul-destroying path to financial independence and "**** you money." Most of them seem to be eating, drinking, and drugging themselves to death. Yeah! Sign me up for adulthood! Miserable marriages, PITA kids, divorce, browbeating bosses, coworkers that want to bully me into conforming to their execrable values, and so on. Yeah, adulthood is just so exciting!
That I prefer fantasy over reality means I'm a bit of a Peter Pan, I guess. But, experiencing the alternative is miserable. If unions were stronger -- if benefits were more fair -- I'd probably leap at the opportunity to "mature." But, since I'm genetic excrement, what's the point? I might as well be euthanized.
