You Can Count on Me

You can't always count on sober and serene,
But you can count on me.

I'd give up reading and writing, quit doing math even,
Before I'd stop being your friend.

You can't always count on clever and cheery,
But you can count on me.

If blood is thicker than water, then what we got is oil
Within this mortal coil.

You can't always count on consistency,
But you can count on me.
