Flies on my window

You flew in my window,
buzzing around my head.
I didn’t ask for your presence
or the thought of you in my head.
But nonetheless you are here.
So I have this new task I must do,
to remove your small nuisance
growing larger inside my head.
So now my brain is focused,
disproportionately to your true size.
You take on new purpose,
as everything else subsides.
You are etched in my focus until,
I can find a rolled up newspaper,
to put your presence out of my mind.
