Today's the day - my book is launched

Tonight at 7 pm my book will be launched.
Am I excited?
Yup
Am I nervous?
Yup
to make matters worse in the nervous department: yesterday I got a brilliant idea. This brilliant idea resulted in one and a half minutes worth of dialogue being added to my piece. The words are necessary. They have to be said. I just wish I had realized this last week. Oh, well, I'm sure everything will be fine. Strangely this introvert enjoys public speaking. Besides I won't be the only one presenting pieces tonight. In fact, it should be a very enjoyable, entertaining night. Your best wishes are warmly received.
