Haircut Dilemma

So, tomorrow I have an appointment to get my hair cut. Which always presents me with a dilemma these days. See, I'm currently not particularly happy with my hair. Growing it out longer is definitely not an option. Thanks to a little bit of the "early-greying-hair Pew gene," I discovered about ten years ago why most older women wear their hair short. Grey hair is rebellious. Even if you have perfectly straight, flat, no-body hair (like me); the grey version of your hair tends to be full of body and wave. It sticks straight out-perfectly perpendicular from your scalp and curls weird directions. It is quite visable when the rest of your hair in still straight, flat, and has no body, so it is plastered to your scalp like glue. You can't pull your hair up into a pony tail or elegent sweep, either. The grey hairs sticking out all over show even more then. A really short hairstyle is the best way to disguise this problem. The happiest I have ever been with my hair was when I had it cut really short when Atom was a baby (probably the only thing that kept me sane through the exteme sleep deprivation and non-stop nursing.) Good thing it could look good with almost no effort, because I never had more than five minutes to spend on it and usually Atom was screaming by the time those five minutes were up. But see, then I had an infant in arms so I didn't worry about looking "old." I was a "trendy" young mother then with a trendy haircut. This image is becoming more and more difficult to keep up with a child in (gulp!) high school. Now I am afraid that a short haircut will make my attempts to be delusional about how old I look ever so much more difficult. This delusion is already being seriously impaired by the fact that I am back in Utah now and sometimes run across high school classmates at stores and such and I think they are their mom or dad. Then I realize that it is a much older version of my classmate--not their parent!! I am also afraid a really short haircut will just cement in other's minds that yes, indeed, I am middle-aged--in case they still weren't quite sure despite all the other obvious evidence. My other concern about getting it chopped short is that I will never want to go through the growing-it-out nightmare again so I will basically be stuck with the same hairstyle for the rest of my life. And (most days) I hope that will be at least another 40 years. My hair complicates this whole dilemma in my mind by playing a trick on me the day of the haircut. It always arranges itself into a gorgeous hairstyle without any effort on my part--so that I start debating whether to get it cut at all. But I am onto it now--I know it will be back to it's horrible tricks the next morning so I'm getting good at ignoring it. So what to do...
