The entire concept of calling oneself gracious is, in itself, ungracious.
I agree with Andy, have fun with it. Unless of course, you're scared to death at being out there and saying the wrong thing and then a "yes thank you" would be acceptable. But from what I know of FIRST kids, bashfulness is not a common trait.
