I've got you under my skin.

You are so much a part of me.
Without you, I'd die.
You've supported me all these years.
You are the one that makes me reach out.
You make me feel warm inside.
You keep me going.
You're so flexible.
You keep that smile on my face.
You are my strength.
You'll grow old with me.
I know we'll change together.
You move me. (superficially and deeply).

Dearest Latissimus Dorsi, be my valentine. If you won't, I'll ask another muscle. Gluteus Maximus, pectoralis major or serratus anterior. no big.

--For the little unromantic in me, and in all of us. *smirk*. Happy V's.
