It was a productive weekend.

The parents are safely back home in Arkansas; my house is clean; the dishes are washed and put away; and life is ready, thankfully, to get back to normal.

Since my parents and I only see each other every six months now, it's commonplace to see changes every time we DO see each other. I think I was most shocked this time by how much older my father looks. He is fifty-six now, and he looks much older. I think a lot of it is that his hair is completely white. Not that off-white yellow that some people get, but a shocking pure snow white.I'd rather have that than grey hair, actually.

My mother no longer colors her hair, for which I'm grateful. I've never really understood why women color their hair to hide grey. I'd say that my mother's hair is now 25% grey; I wonder how many of those I put there?

While driving back from buying my lunch today, I was thinking about the concept of age, and how much it matters to people. We have a twofold conception of age in this society—we are obsessed both with our chronological age and our mental age. Due to our obsession with numbers in base ten, we see numbers that end with a '0' as being somehow more significant than others, more indicative of a stage of life, than any number in between.

Normally, this isn't a problem. But things get interesting when mental age doesn't equal chronological age. We as society members expect everyone to mature somewhere along an expected scale. We have certain expectations about the emotional maturation of two-year-olds versus forty-year-olds, for example.
