Yeah, let's save this for the archives:
"Jill, I wanted to say thank you for teaching our class. I admire your abundance of enthusiasm for sharing your passion. I felt you helped in breaking down my inhibitions with all those silly warm-up games. I believe that really paid off in the show last night. I wouldn't have missed it for the world!!! I hope to take the next level course in the fall or winter. Thanks again!!!"
