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
