["I'm in a wedding party tomorrow, and I've been called upon to give a big toast during the reception.", "Wow, that's such an honor.  How do you feel about it?", "I am deeply touched and I've got everything laid out, but it's in front of a large amount of people and I'm sweating bullets over it."]
I'd be very nervous too.  I get stage fright.
I've got to give a big speech at a wedding tomorrow and I'm getting shaky just thinking about it. I wish I could just get it over with.
