歌詞: Tim McGraw. I Didn't Know It At The Time.

I thought that my first love would be my wife
But in junior high she moved away from here
I thought Johnny would always be my best friend
I haven't talked to him, in 15 years
Back when I had those fights with my old man
I never thought he'd be....an old man

And I didn't know, all those years ago
How the years would go flying by
Thought I knew it all
But I was wrong
And I didn't know it at the time

I never thought good jobs were hard to find
Til I let my pride cost me one
I never thought my whole life would change
Til I heard the doctor say, I had a son
I never really thought that I was lost
Til I heard my dying mother sing Old Rugged Cross

And I didn't know, all those years ago
How the years would go flying by
Thought I knew it all
But I was wrong
And I didn't know, I didn't know it at the time

Oh, I Thought I knew it all
Oh, But I was wrong
And I didn't know, I didn't know it at the time

I didn't know, didn't know, didn't know

I didn't know

Ohhh, I didn't know
