Answer the question based upon the following this :

If I only could, I'd be running up that hill

If I only could, I'd be running up that hill

If I only could, I'd be running up that hill If

I only could, I'd be running up that hill It

doesn't hurt me

Do you want to feel how it feels?

Do you want to know that it doesn't hurt me?

It's you and me

And if I only could

I'd make a deal with God

And I'd get him to swap our places

(Runnig up that Hill by Kate Bush)
