Imaginary Friend

No one has seen me

Some claim to have known me

Some want to measure me

All like to use me

I am a thought experiment

An experiment that can be thought of

But can’t be performed

I am like a cat enclosed in a box

I am dead the moment box is opened

Let me remain encased

To keep me alive

Let me reside in your imagination

I can’t be appraised

Faith keeps me alive

I am your imaginary friend

Real as well as virtual
