You ought to know by now
Love is the look in my eye
Lovin' the way you smile
When I say 

"I wish you would stay"
You bring out all the youth in me
I laugh and cry out all the truth in me out of love
You should know by now

Haven't you felt by now
Just what it's like to be loved
Knowing that certain touch when you're sure
Time won't give you more

You bring out all the best in me
I want to hold you till you feel the need
You should know by now

If I could just find the words
I wouldn't be left so lonely
I'm you're my one and only
And I'd show you how

Every move as smooth as silk
Say you will
Stay you will

Hasn't it crossed your mind?
Haven't you known all the time?
Honestly tell me now has it shown? 
How much love is grown?

The way I tremble at the sight of you
I want to learn to love you through and through
This I'll vow
You should know by now

Hmm by now
You should by now
Don't you think you should know by now?
