Generation gap

The highschool in my town has classes for those interested in perusing child care. Each Spring, they have a mini preschool session where 15 lucky children get to go and be Guini Pigs for a bunch of teenagers.
Good birth control? Probably!
Logan was one of the lucky 15 this year.
It's 8 sessions, 1 1/2 hrs each.
He absolutely loves going, seeing he's an attention hog and all! He gets 1 teacher and 15 students dotting all around.
Today when we walked in, I heard about 6 different teens say, "ooh! It's Logan!" or "yeah! My little buddy is here!"
Very sweet and cute.
Now, I've been out of highschool for 11 years now, yet, I still feel like I am the same as when I was in highschool. OK, maybe not the same, but I sure feel like I basically LOOK the same.
I mean, I don't look as though I'm approaching 29. (TKW, Anne...shutup!)
I still get carded most of the time. When I DON'T get carded, I often wonder why. I'D card me.
So, here I am walking around thinking that I'd fit right in appearance wise with a bunch of highschoolers, because of course, I haven't changed.

RIIIGHT!
This 'highschool preschool' as we call it has opened my eyes.
I do look 29. OK, maybe 27.
I look at these kids and really realize how YOUNG they look.
They are sweet and fresh and trendy and put together.
I come in with my 2 kids, one slobbering over me fighting off a monster of a cold, the other with a fresh chocolate milk stain on his upper lip that I didn't notice until we left.
My hair is in a messed up ponytail.
I arrive in my minivan.
I have a diaper in my purse.

My false illusions on the subject of age and appearance has vanished.

It makes me wonder if I'm alone in the matter.
Do you feel like you look younger than you really are?
Are you finding it strange to really realize your true age, or are you completely aware and not bothered by it?
Very curious.
