UNINVITED FRIEND

You arrive at my door once a month uninvited
I don't remember extending you an invitation  for your presence
But here you are without fail
You are the friend people never want to see, yet find someway to maneuver your way back in my life when I thought I had finally gotten rid of you
You show up on my door step knocking and I am all too willing to let you in with a half hearted smile
You have the persistence   of a Jehovah witness
Going door, to door, to door
You showed up one day and never left
You wore out your welcome really quickly
I mean, you did leave, but only for a moment
I endure your unwelcomed presence
One week a month, eighty four days out of the year, that is if you are on time, as usual
If you come regularly, oh and if you're not late
You are the sweet, but bitter thing
You never cease to annoy me, you constantly hang around
It is when you don't hang around, I have to worry
It is a catch 22
I put up with you one week out of the year, eighty four days out of the  year
You bring me grief, pain, mood swings, and the appearance of a mini crime scene
But if I don't tolerate you,I will be without you for nine long agonizing months
Left to face the consequences of your disappearance
For 18 long years
