(a cappella)
Ohh.. ohh.. ohh..

Justin:
She was my once in a lifetime
Happy ending come true
Ohhhhh i, guess I should have told her
I thought she knew
She said I took her for granted
That?s the last thing I would do
Oh 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

Joey:
A heart full of words left unspoken
Now that we?re through
I?d sell my soul to have this silence broken
Oh I thought she knew (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

Justin:
She was my once in a lifetime
Happy ending come true
Woahhh 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 (I thought she knew)
Ohhhhh I thought that she knew
