When did your DDs start to have crushes? Any advice on "managing" them in pre-teens?

I think DD(10) is experiencing her first crush at the moment. She has started to go a bit red and giggly whenever we mention the name "Josh". He is a friend of ours who is often around.
When he is actually there, she behaves normally. It is usually when he isn't there that the giggling and blushing occurs. He is the only Josh she knows and it is definitely him.
Josh recently got married and DD came to the wedding with us. We let her give Josh and Annie our wedding present, for which she got a hug and a kiss on the forehead from him. It was completely innocent of course, but she went fluorescent pink and was speechless for several minutes. As I drove her to her Granny's afterwards, before the evening do, she came out with "if Annie decides she doesn't want Josh any more, I want to marry him." I have told her that that kind of talk is okay with her girl friends or me, but not to go shouting things like that out. I'm not too worried though, she isn't really a "blurter" like some kids I know.
I'm inclined to leave her to her daydreams, which are more in line with princess stories than anything nefarious, and DH is in agreement. We both remember having crushes from much younger ages than 10, and usually on older people - my first was my cousin's boyfriend and his was his friend's mum.
Has anyone else dealt with this and am I doing the right thing?

awh cute! I had a crush on a male teacher at that age...oh and Michael J Fox too. Haven't dealt with it myself, but you sound like you're doing exactly the right thing.
