This is it

Well this is it that day is here
That day I knew would come when you would leave me dear
Well here I sit while teardrops fall
And wonder why I care when you don't care at all
But I'm a fool that way from a way back when
A fool who take you back if you'd come back again
But this is it you're gone you're free you'll find another love but this is it for me
Well this is it that day is here it's no surprising yet I can't hold back the tears
Well here I sit and try to guess how such an empty room's so full of loneliness
Well even the clock has stopped somehow I guess you knew
That time's run out from me it's over it's all through
Yes this is it you're gone you're free you'll find another love but this is it for me
