My dear perfect friend/fiend

My dear perfect friend
Or should I say fiend?
That’s what I’d like to say
But I won’t be able to today
As you don’t exist at all
And the tale is far too tall
There are others as alternatives
But it’s not my best friend who lives
My perfect imaginary friend
Without you I’m just a fiend.

If you were to exist and be
In all reality’s simplicity
I could talk to you forever
To help me face the weather
And to decide on the best action
And keep me from vile distraction
I’d ask you for all the help I might need
For all advice from selflessness to greed
But you are only an idea in my head
So really you’re virtually completely dead.

My dear perfect friend
Or should I say fiend?
