N'sync

Do do do...
[repeated]
She was my once in a lifetime
And the 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 say the same,
Only myself to blame.
I should've known,
I should've known.
She was my once in a lifetime,
And the 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...
