I have a funny feeling that there's going to be a lot of that kind of over-the-top stuff. The amount of shrieking and shouting that the main character's been doing could get very irritating if it keeps up when she returns as an adult.
Funny you should mention this, Kathleen. "The laugh" has become a common household joke in my family. The cheerful smile accompanied by a forced laugh and a nod, so often put on by the characters in these dramas, always causes ripples of true laughter to pass through our living room.
I think one of my favorite examples of this was in the recent "Great King Sejong" series, when Sejong had been made the Crown Prince (if my memory serves me right), he and his friends and political buddies were all playing a game that resmbled golf or crochet. They were all in a very good mood, which made the scene even better: at every single good (or semi-good!) hit, they would all look at one another with shining eyes, grin, and say a monotone "Ah-ha-ha" or "Oh-ho-ho" while doing the bubble-head-nod. I love it! ;D
