Looking for a way to gracefully exit

at the Temple Bar
here in Bellingham
with the owner
helping to organize
the showing of an experimental film
invitations have been sent out
there is an air of exclusivity
to everything
a limited showing
only a select crowd
I keep forgetting times and dates
and the owner
jokes with me about it
but is getting exasperated
shortly before the film starts
I realize I have forgotten
to invite any of the people
I said I would
and know that I cannot stay
but I don't mention this
to the owner
since it would just be
one more thing I had forgot
and she is concerned about seating
and limited space
I am holding a few invitation / tickets
looking for a way to
gracefully exit
