he was just very, very playful and he encouraged and allowed that side of him to come forth as he grew older. he knew that was the only way he could survive the cruelty of the world around him and the hand that was dealt him.
I am very playful, but I don't show that side to people I don't trust. Michael, I think, trusted people instinctively. hence he showed that side of himself to most people he met. and then most of them broke his trust, at which point, he cut them out of his life.
he was a trusting soul. childlike and godlike. hence why he had to leave us so early. those kinds of people do what they have to do... what they are here to do. once that is accomplished, they're free to leave. I only wish he'd had had more days on this earth to be with his children whom he loved so much and vice versa.
also, while I know that this film (This Is It) has been dedicated to his children, I think Michael -- in his heart -- also dedicated this film to his fans. I think he knew we have given him unconditional love. he knew that even more during and after the 2005 trial. he knew how much love we had for him and he knows now how much love is pouring forth for him.
