You are

I know you probably wonder from time to time
what you mean to me.

So I'd like to share this thought with you, to tell you that
you mean the world to me...
Do you know how important you are to me?

Think of something you couldn't live without...
and multiply it by a hundred.

Think of what happiness means to you...
and add it to the feeling you get on the best days
you've ever had.

Add up all your best feelings and take away
all the rest...
and what you're left with is exactly how I feel about you.

You matter more to me than you can imagine and much more than
I'll ever be able to explain.
