Do-do-do-do...

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-do...

She said I took her for granted
That´s the last thing I would do
Whoa, I´ll never understand it
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 have known
I should have known

Do-do-do-do...

A heart full of words left unspoken
Now that we´re through
Well, I´d sell my soul
To have this side let spoken
Oh 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 have known
I should have known

Ooh...

She was my once in a lifetime
Happy ending come true
Whoa, I guess I should have told her
But I thought she knew
I thought she knew
I... thought she knew (I thought she knew)
I thought she knew
Ooh...
I...thought...that...she...knew...
Knew-knew-knew-knew...

Knew-knew-knew-knew...

Yeah-oooo-oooo-oooo...
