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 keep pacing back and forth going over everything. I hope it works out!
