A Love Poem

You were reading a book as I lay next to you with my head on your chest.  Your arm was around me so you had trouble turning the pages.  You asked me to turn the page for you and I was glad to.  After the first page turned, I heard your thumb slip to the bottom of binding and I turned the page again.  What seemed like an equal amount of time passed before I heard your thumb make room for the page to turn once again, so I turned it.  I was listening to your heart beat the whole time and it kept such perfect rhythm that I used it as a timer to anticipate the next time your thumb would slip down to make way for the next turning page.  You read an average of one page per 90 heartbeats.
