If I were a...

If I were a rock I'd be big and gray.
I'd sit outside all of the day.
Until you came and scooped me up
And used me as a paperweight.

If I were a toad I'd be green.
I'd hop about, never mean.
Until you came and kissed my mouth
And then you'd have your lips to clean.

If I were a tree I'd be round and tall.
The sun would shine, my shadow would crawl.
Until you came and chopped my trunk
And then upon you I would fall.

If I were a friend I'd be here for you.
Trusting each other, our friendship grew.
Until the day you told me lies
And then out the window, our friendship flew.
