absence of dad

when my twin and i curiously waiting for our name to be called on "Award of Excellence" day in school, i saw my mum was sitting alone in the crowd watching us with a little smile on her face,
when we were registered in boarding school, my mum brings us by taxi to the hostel and go back by walking alone to bus station,
she never knows that her twin babies were watching her leaving the hostel from their room window,
my twin never knows that i was crying at that moment and perhaps she was crying too but i never know.
