It’s my barrier between worlds
between introvert and extrovert
between safety and anxiety

I’m open to the idea
of using it
but for the most part
it’s closed

Only a few inches thick
blocking out all noise
keeping my thoughts inside
for no one else to hear

It’s the last thing
I close before embarking
on my daily journey
but it’s the first thing
greeting me
upon my return

I welcome it
with a turn of a key
and a slight push
it’s rather symbolic.
