is this normal from a 9 year old

Does anyone's child become over excited when you get visitors around? My 9 year old daughter becomes over excited, her pitch of voice changes and just generally hyper active. Is this normal or should it be something to worry about?

I have an 8 year old and an 11 year old DD and I honestly don't think there IS a normal in terms of pre pubescent girls :)

Does she have friends? Is she doing ok at school?
