A Note To My Yoga Instructor

Dear Micah,

What in God's name did you do to us on Saturday? Your class did not feel out of the ordinary. There weren't any poses I was previously unfamiliar with. So why, then, do my hamstrings feel as though they are ripping in half whenever I try to lower myself into a chair or run down a set of stairs? Why, Micah? WHY?

Painfully yours,
Jessica
