If I'd Only Known

If I'd only known, I could have said something sooner But I didn't, so I didn't, now it's done The last thing I'd do was the first thing you did What we once had is all gone I see it all, a little too clear Too clear for my own good "Let sleeping dogs lie" is a good rule, I'm told I only wish that it would If I'd only known, I could have said something sooner I really did think it would last Now it's too late, it's over now My future is all in my past
