I know I’m sane !
I know this because you haven’t put me out on the street yet.
Because the government still asks for my taxes and expects me to pay them.
Because the space aliens haven’t come for me yet.
Because even though every manic driver in the world lives within 40 miles of me and they all get on the same road I am on and try to get me they haven’t succeeded in murdering me because I still have my wits about me.
And finally and most importantly because when I talk to myself NO ONE LISTENS !
