Lyrics:

Do-do-do...
[repeated]

She was my once in a lifetime,
happy ending come true.
Oh...I guess I should have told her,
I thought she knew...

Do-do-do...
She said I took her for granted,
that's the last thing I would do.
Whoa...I'll never understand it,
'cause I thought she knew.
I thought she knew:
my world revolved around her,
my love light burned for her alone.
But she couldn't see the flame,
only myself to blame.
I should've known,
I should've known.

A heart full of words left unspoken
Now that we're through
I'd sell my soul //to have this silence broken//
I thought she knew my world revolved around her
My love light burned for her alone
But she couldn't see the flame
Only myself to blame
I should've known
I should've known


She was my once in a lifetime,
happy ending come true.
Whoa...
I guess I should of told her,
but i thought she knew.
I thought she knew,
I thought she knew...

Ooo...
Mmm...
Oh...
I though that...she...knew...
Yeah-oooo-oooo-hoooo...
