Past - hm?

Past popping up
in my emails- on my shores -
why I do not know
my parents - siblings -
great-grands of whom
I know nothing
and I know I should
feign a true interest
they are part of
one's genetic make-up
and they are in my
children's genes
yet - there is nothing
I can physically do
to short circuit that
so - why bother
except for historical
purposes and ...yet
if I do not know my past
will my children be
obliged to remake
their granny's mishaps
or has the world changed
so - that is my today's
question -
and the answer of course
is that I am crazy
because the more I know
'bout my past -
the more ...... hm!
