i remember being that age.. seeming it was only 4 years ago. Personally... take it easy with her. Your kids have good manners, because you taught them. But how do you know she has had the saame up bringing? She will be shy and probley even talking to you would make her get the butterflies. My advice is.. dont get your son to talk to her, thats embarrasing for both of them. Just encourage her to talk to you to start off with. Ask her how she is and how was school etc. Dont wait for her to say hello, say hello first, so she learns its what you expect. Once she becomes more comfortable with you, things will run much mor smoothly.
