20/20

When I think of all I put you through
 Always taking you for granted
 I never saw it from your point of view
 Blinded by the double standard
 You were tryin' to tell me all along
 Something in the love was missing
 You said, "It's not too late to get it back"
 But I just wasn't listening
 If I knew back then what I know now
 If I understood the what, when, why and how
 Now it's clear to me
 What I should have done
 But hindsight is 20-20, 20-20 vision
 ♪
 Now I see it in a different light
 I've been losin' you in stages
 Give us one more chance
 I'll get it right
 Girl, you're gonna see some changes
 If I knew back then what I know now
 If I understood the what, when, why and how
 Now it's clear to me
 What I should have done
 But hindsight is 20-20, 20-20 vision
 Takin' time to catch up on some history
 Tryin' to figure out what went wrong
 With you and me
 And it doesn't really matter
 What's been before
 But I know there's no future
 With you walkin' out that door
