@DrewDad,
Me too! I think it's very sweet. And funny.
I think Zach is happy with how things turned out overall.
It's part of what I really love about this community, that the kids all know each other so well and they're rooting for each other (usually).
Yesterday at her softball game, one of her friends came up and asked me what I thought about the whole thing. I said I wasn't thrilled about how young they are, but I like Zach, so <shrug>. We chatted for a while. He wanted to know if Zach was at the game and seemed disappointed (in Zach) that he was not. Then he said, apropos of nothing in particular, "Sozlet is a really nice person." I awwed and thanked him for saying so, and said "I certainly think so but it's nice to know other people do too." He said, "I think Zach thinks so too."
And he's not the only one, all these kids want to come up to me and talk about it.
You're very right that she would've just asked out Zach if she felt the need to. (Yesterday she was texting with another male friend who is a friend of Zach's, and after a while the friend said "I don't think we should text anymore." She asked why, and he said he didn't want to get in a fight with his friend. She said she was sure Zach wouldn't mind, the friend still wasn't sure, so she then texted Zach to ask. He said "of course I don't care" before moving on to other things.) (I don't know why that parenthetical leads from the first sentence, something about them not being all gender role-y about this. They've gone dutch on all dates so far, etc.)
The way she's explained her feelings towards Zach to me is that they've been close friends and she definitely liked him, in a wants-to-spend-time-with him way, but just wasn't sure about the crush part of it and thought most of the people in her grade who were dating were pretty silly. When she realized recently that she did in fact like him as more than a friend, she just banished the thought because she didn't want to deal with it, and admitting it meant it getting out (since she has about five friends from whom she cannot hide anything, even if it's unspoken).
Edit: I have to add what she told me about when she realized. He's always coming up with harebrained schemes -- they should start a band, they should design a videogame, etc. A couple of weeks ago he came running up to her and said "we should start a food blog!" For some reason that was the moment. It's very him.
So overall it worked out pretty well I think. Thus far. Fingers crossed.
