Ponder the following if you will, the next time you see some one of unbalanced nature, talking to themselves.
Example of one person talking: "Shut up" "I don't. Now just leave me alone." "7 o'clock." "Bacon." "Mexico." "Tuesday I guess" "Whatever. Maybe." Now consider another person, on another continent, also having a conversation with himself: "Got I have a match buddy?" "Gees sorry. You just look like the kind of guy that would." "Can I trouble you for the time?" "What are you eating?" "Where are you going?" "When are you coming back?" "Visiting relatives?" If you put the two pieces together they actually make sense. Makes you wonder if some mental patients are just a step further from the 1990 yuppie - two people separated by thousands of miles but connected with a different type of cellular communication. Merry Christmas.
