You should know the way I feel I thought you were all alone Cause you told me that you missed me on the telephone Boy, I can't explain the way I feel right now You and I have been together for quite some time I never knew you were wrong all along All I wanna know is Why is it that I'm the last know? Why is it that I'm the last know? I have noticed things have changed Cause the time we shared together's slowly fading away I didn't think that you would do this How could you have been so cold? Thought I'd be the first to know You and I have been together for quite some time I never knew you were wrong all along All I wanna know is Why is it that I'm the last know? Why is it that I'm the last know? Why, oh why did I live a lie Thought I'd be the only one Boy, you found another one Cause the love shared today I thought forever would remain You were with somebody else You were thinkin' of yourself You and I have been together for quite some time I never knew you were wrong all along All I wanna know is Why, oh why, oh why did I Even have to live a lie How could you have been so cold? Thought I'd be the first to know Why, oh why, oh why did I Even have to live a lie How could you have been so cold? Why am I the last to know? Why is it that I'm the last know? Why is it that I'm the last know? You came into my life You seemed like Mr. Right What you did to me baby See, you're no good for me Guess you really didn't give a damn I thought you were my man What you did to me baby See, you're no good for me I could never imagine You would be with someone else And I would be alone
