Missed that. If that's what you decide to dislike the guy on that's your prerogative. He was basically talking to the younger him, in a sense.
Is that even a thing? I mean, quite possible he suffers from narcissistic personality disorder. Tell me it's not about him..
People write letters to their younger self all the time... I don't find that narcissistic. Entertainers as a whole do this more often than you guys are making it seem out of the norm. He's a celebrity, not a regular joe blow like you and I.
