(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
