But alas, in 1964, when I was nine, my young life
shattered into pieces once again. My mother passed away
after an illness of just 15 days. She had been the anchor of
my life. And how I missed her. But little children are
resilient. My maternal grandmother was staying with us
and my mother's widowed younger sister came to help out
with us. So well did my aunt fit into our household that in
two years my father had married her: she become our
mother and her only daughter become our sister.
