Is this normal???

This year Chlo is having a great time in school. She's made lots of new friends, which actually doesn't surprise me. She's such a friendly person who likes everyone. On the first day of school she saw who she called "A cute boy" on the bus. Since then we've heard new stories almost daily about him. From what I can gather he's pretty much the class clown, he likes to make people laugh and see them smile. This past week Chlo has found herself sitting with him now on the bus. She brought home her birthday poster on Tuesday and I guess her new "Friend" kindly kissed it :) I guess he also kissed her arms with what he called "fishy kisses". I guess he's going to be a fish for Halloween. Yesterday when I picked her up from the bus he looked out the window and blew her a kiss... Is it normal for 6 year olds to be like this??? I do have to admit though, he's a WAY cute kid, she did choose well, and if he's nice too - that's even better! :) Maybe because I'm such a hopeless romantic it's rubbed off on her?? Dave and I have even come to calling her "Brock lover" and she smiles every time. Even kids at school are asking her if she likes him. Funny thing is, he's not even in her class. She just met him on the bus. I think Dave and I may have our hands full! (And then you ask, "who is the crazy mother on the bus taking pictures of the whole thing"??? Alas, I am a crazy blogging fool who has to document everything :) )
