The Art of Disappearing
When they say Don't I know you?
When they invite you to the party
remember what parties are like
Someone telling you in a loud voice
they once wrote a poem.
Greasy sausage balls on a paper plate.
If they say We should get together
It's not that you don't love them anymore.
You're trying to remember something
too important to forget.
Trees. The monastery bell at twilight.
Tell them you have a new project.
It will never be finished.
When someone recognizes you in a grocery store
nod briefly and become a cabbage.
When someone you haven't seen in ten years
appears at the door,
don't start singing him all your new songs.
You will never catch up.
Walk around feeling like a leaf.
Know you could tumble any second.
Then decide what to do with your time.
I love that last part. At first glance I thought this poem was about someone who is anti-social. But it isn't. Instead the poem seems to me, to end with a message which is "this is how I am intentional".
