Lyrics:

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
