Nostalgia

With certain vulnerability
the virus can spread;
blood buzzing
nerves alert
to the point reached
where one word
a smile
an old song
a town passed through
are sign points
to who you once were
where life once was
and with whom.
The present gets lost
overcome by
once-upon-a-times,
mistakes not learnt from.
A non-productive
disease
tearing holes in the soul.
