I just love this thread too. My friend and I walk together a couple of times a week. We both have 13/14 year old sons. They used to hang out together, but they've never gone to school together, and now they have their own friends, etc. We both, my friend and I, are just loving this age - listening to them when their friends are over, or we're driving them someplace. They're sweet, and strange, and funny.
My dd is 11, and is also sweet, and funny, and fun. But she and I are both emotional, so we clash a bit more. But we're really close all the same.
I'm finding that this time in my parenting life is so fulfilling. The kids are both going out into the big world now, and discovering who they are. Their lives are going in different directions - even though they homeschool, and spend a lot of time together, they're so different in their interests! Tonight, they were playing together on the family room floor - rolling around and laughing together, just like they did when they were little. I love them so much!
