Interesting question that I wholeheartedly agree with the sentiment, having asked it myself. Well, not about myself - I ain’t a girl or a woman.
See I have trouble addressing the female gender because I’m conditioned to say “girl” for anyone my age or younger. Whereas women are older than me. Only problem, that age gets older each year. I think it does stem from the fact that I don’t see myself as an age (and thus have to recalculate whenever asked - How old am I again…?) I wonder when or if I will ever consider myself an adult. I have my own job, pay my own bills, etc. And as long as I don’t see myself as and adult, then anyone my age can’t be an adult. Thus it shocks me to meet people my own age with three kids and two divorces. Or something like that.
Now that I’ve agreed with everyone, I offer a little insight, for what it’s worth. How come we in this culture don’t feel like adults at the age of 30 and beyond, but in other cultures people become adults as young as 15?
Perhaps it is because we lack the notion of the trial by fire, initiation ritual to adulthood. In many indigenous cultures, a person must undergo a trying, often life-threatening, ritual trial that establishes adulthood. This may involve a solo trip through the jungle, a hunt for a large predator, a drug-induced catatonic state and hallucinations, an initiation fight (like gang initiations), or other variations. All of these rituals involve the person taking responsibility for emself, and facing some grueling challenge alone, to depend only on es own merits and abilities. And once the trial is completed, the person is viewed by everyone as an adult, and takes on adult roles and actions and duties and behavior.
What about us in our “modern” culture - don’t we have initiation rituals? What about graduation (high school and/or college), that typically marks the end to living at home and the beginning of supporting oneself? What about turning 18 and registering to vote, just because you can? What about marriage, forming your own household (not just moving out), and starting a family? Buying a house?
All of these are possibilities that could serve as adulthood initiation rituals. Why don’t they? Is it because they don’t involve a dramatic “trial-by-fire” experience? Maybe. We have a culture that regardless of how we desire to break free of your parents’ control and establish ourselves as individuals, we still tend to hang around and rely on them for lots of things. Like helping with expenses during college.
That’s one guess.
Another thought - our culture seems to glorify youth and look down on aging. Is it perhaps a subconscious desire on our parts to retain youth by refusal to become adults?
Okay, I’ll offer up these two suggestions to get the mental juices running, let’s see what others think.
