'i will be busy all day concealing a violent attitude towards authority and I do not wish to be disturbed'

On Wednesdays I like to post an older card like this and then spend the rest of the day writing letters to various newspaper editors requesting more coverage of the small African nation of Bunwabe. I sign the letters 'concerned'. Bunwabe is a country I completely made up. I believe that one day I'll know why I do this.
