Sitting in the train station one day waiting for a train i observed a Guy in a business suit waving his arms in explanation as he was seemingly talking to an invisible person for a few minutes. Thinking "This guys nuts!". He then smiled touched his ear and stopped, it was a Bluetooth he was using.
Do you think Those who talk to the Dead or Clairvoyants find it easier communicating with the "Dead" on a busy open Street since the invention of the Bluetooth ?
