Knees.

Your kiss can bring me to my knees.
The knees you pushed me down upon yesterday, with your words.
The ones I stayed down on, scraped and bruising, hurting elsewhere.
The same knees you cleaned off with I'm Sorrys and tenderness.
And then you kiss me, and I'm down on them again.

I liked this so much, I took this from my other blog, Open Secrets, and put it here as well.
