[Verse 1]
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

[Chorus]
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

[Verse 2]
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

[Chorus]
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

[Verse 3]
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
Oh, I didn't know
