Sure, I learned a few other things from my reunion, such as 1. Thirty years puts a whole lot of things in perspective; 2. Who you've become on the inside is infinitely more important than how many 'protective layers' you've added to the outside, and 3. If you're going to wear beautiful open-toed shoes, don't go dashing over to hug someone who is wearing steel-toed boots, because your take-away from the reunion might be a broken baby toe. Seriously. Ow.
But the main thing I learned at my high school reunion was the kind of Mom I want to be to my teenaged kids. In the neighborhood, at least, of the one I had.
