Skipping Towards Maturity?

it hit me: getting older.

that's pretty ridulous when i stop and think about it, but i just got off the phone with Geico to get my very own car insurance. yeah i know, i'm gonna be thirty in a couple of months, i shoulda had my own insurance, like 10 years ago, but look at the facts:
1) i just got my drivers license 6 years ago.
2) i just moved out of Ma and Pa's house 4 years ago (then moved back FOR a year, after a year).
3) i just got a real job, a year and a half ago.
4) up until a year ago i had debt coming out the wahzoo.
a friend of mine had a revelation, not too long ago, that her life no longer fit into her car. This was her epiphany of her own maturity and responsibility. Now i'm looking around and all the signs are pointing towards some sembelence of stability and maturity:

1) i've been in a monogomous relationship for almost 3 years (September 24th). before this my longest relationship was barely 5 months (the last 2 were spent in totally different zip codes)
2) i've got a job that doesn't require a name tag or a folding board.
3) i haven't gone to bed on a weeknight later than 11pm in almost 2 years (if i do i'm completely useless the next day)
4) i've got my own garden.
5) i cook dinner 3 nights a week in my own kitchen.
6) i'm engaged.
7) my student loan is almost paid off.
8) i've got more hair on my ass than on my head.

when did this happen? when did i stop going out all night to clubs and bars? at what point did piercing my ear or tongue start looking like "something i should've done when i was a kid"?
i don't feel old (except for the occasional back pain and need for a nap). i still look around at people a few years older than me (40) and think "man he's old". are there kids in their teens look at me that way!?!

the phone just rang and i was called Ma'am. why couldn't it have been Miss?
