To you I'm just a man who let you down   The one who never gave you what you need   It's true I wasn't always around   Back when you were reaching out for me      I know you think I didn't care   You say I'm just the hurting kind   I know you think my heart wasn't there   But I'm begging you to think it through one more time      'Cuz you don't know a thing about me   If you don't know how much I miss you   And you don't know a thing about me   Unless you know how much I need to be with you      Well I see the mistakes I made   The way I acted carelessly   But if you don't know how much I need your forgiveness   Then you don't know a thing about me      If I could just go back and make it right   And take the tears away, you know I would   I'd come to you with no excuse tonight   Just a prayer that I'll be understood      You tell me that I'm never gonna change   How I'll always be the same old guy   You think there's nothing left for us to say   Before you write me off, take a look in my eyes      'Cuz you don't know a thing about me   If you don't know how much I miss you   And you don't know a thing about me   Unless you know how much I need to be with you      Well I see the mistakes I made   The way I acted carelessly   But if you don't know how much I need your forgiveness   Then you don't know a thing about me      If you don't know how much I need your forgiveness   Then you don't know a thing about me   No, you don't know a thing about me   You don't know a thing about me   You don't know a thing about me
