I agree, and would add that there is an element of emotional maturity as well (which basically, for me, can be boiled down to "Do Unto Others . . . ").
I will admit that the collection of “adult accoutrements” (i.e., a “real” couch instead of a futon, matching dishes, a plentiful supply of Kleenex and Q-Tips) was once extremely important to me in making me feel like I’d finally reached adulthood.
Now I’m certain that you can get there without the Q-Tips. 
I’m also one of those people who has no desire to be younger; I have a sweet but domineering mother, and so am quite glad to have reached an age (and a level of adulthood) where she no longer has any tangible authority (namely, purse strings) over me.
(Although she still tries . . . SkipMagic and I are about to be in the market for a house. Mom wants us to get a move on, already, so she’ll have someplace to come spend the night. But I digress. I was telling her about a BEE-YOO-tiful house I found online, and she asked where it was located. I told her, and she declared, “If it’s that close to the inner city, you’re not buying it”. And the truth is, we’re NOT buying it, because (a) someone else is buying it (I drove by and saw a “Contract Pending” sign in the yard), (b) it’s a little out of our price range, and (c) I’m not afraid to live near the inner city, but this particular house is pretty much right at a major intersection, and I don’t want that, even if (a) and (b) weren’t true. But I gotta wonder, how old do I have to be before these little “declarations” on the part of my mother stop making me want to run right out and do the exact opposite of what she’s telling me I’m going to do? I think there’s a little maturity issue I need to address . . . )
I’d NEVAH want to be 16 again, I can tell you that!
I am also, however, a person who believes that as an adult, you are absolutely entitled to make choices that other people may find questionable based on prescribed age-appropriate behavior. For example, I like to shop for clothes in teeny-bopper stores. I like the styles, and for the most part they’re cheaper than “adult” clothes, because they’re being purchased with the allowances of 13-year-old girls across the nation.
Now if only I could figure out how said 13-year-old girls manage to sit down in these pants without showing three inches of butt-crack . . .
:eek:
