A few times a week Bob hallucinates, sees and talks to people that are not in the room. This weekend when Carr ( 6 year old grandson) was here-- he was backing Bob up and agreeing . He Said "yes-- grandpa I see the people too.. they are saying they want cookies"
Grandpa Bob was pretty happy that someone else confirmed his suspicions ( even if it was a 6 year old with cookies on the brain) and also that they got cookies out of the deal.
Maybe we have ghosts..and only those two can see them?
