Isolation, real or imagined, is a big part of battling depression.

the book

what is this book if not a defence
against eating alone in a restaurant
or better still, a pen and a notebook
gives you the excuse to look up and around
stare off into the distance, discretely
people watching
observing the dress and mannerisms
of people around you can bring insight
or not
sometimes it’s easier than looking inside
but what to do as the room empties out
and the people are gone
and the staff are still
what then
back to the book perhaps
anything to stop the introspection
the loneliness
and isolation
