You can tell when Michael misspoke? Only Michael can do that. Are you..... ?!?
Sure. Even Larry King knew he misspoke.
When someone repeatedly says it was Terri's wish, time after time, interview after interview, and then one time says "we" didn't know when referencing her parents, that's your clue.
But you think that one time was the truth, and all the other times were errors? And the sworn testimony of others who said it was Terri's wish -- those were mistakes also?
