If I were a book

If I were a book,
I wonder how I would be?
Would I be an adventure?
or would I simply not be?

If I were a book,
I wonder how I would be.
After what I tell you,
would you still need me?

I could tell you about my life.
All about my wordly dealings.
I needn't be shy,
I could express all my feelings.

I could tell you when I am happy.
I could tell you when I am sad.
I could tell you when I feel good.
I could tell you when I feel bad.

I could tell you what I like.
I could tell you what I hate.
I could tell a tale of destiny,
I could tell a tale of fate.

I could tell how much I love you,
How much you mean to me.
Say, if I were a book,
would you still read me?
