Armpit Hair

OK. So yesterday I mentioned that Joshua had gone fishing with a friend recently. They were out all day, and he didn't use any sunscreen. He got some serious sunburn.
It hurt him to even have his shirt on, so for that evening he ran around the house shirtless. As we were sitting at the table, Joshua leaned back and put his hands behind his head. And that's when I saw it.
I mean, it didn't register at first. I had to do a double-take. But at the second look I was sure of what I saw.

My little boy has armpit hair!

And I couldn't understand how that could be. I mean, I guess it's been a while since I've looked at his armpits, but I'm quite sure the last time I looked - there was no hair.
And now there is.
But he's only 13. He just lost another baby tooth, for crying out loud! I don't feel ready for armpit hair. *sigh*

I know. He's growing up. At 13 he feels like he knows all there is to know about life. I remember. I was there. (Ten years ago. LOL!)

It's just that, well, the only other armpit hair I see on a regular basis belongs to my husband. And I can't put the two of them in the same category.
Not yet.
Yikes!
What's it going to be like in a couple years when Joshua starts driver's training? To see him behind the wheel of a car???

I am not getting older. I am not getting older...
