His eyes are empty. There's nothing there. He always appears alone, my guess is, especially with the school room, he was never accepted by peers. I'd guess that one of two things going on with the girl thing is that when younger he had a friend who was a girl, probably the only friend he found companionship with, somehow they parted ways for reasons unknown but he sings about her loss. Or he suffers from schizophrenia, double personality, but I doubt it. I think he targeted the parade because he wanted to target kids because he was never accepted by other kids in school. The dress up at the Trump concert maybe a connection to the picture on the wall of JFK, couldn't get a gun into the rally would be my guess but I also think the targeting, if that was what he was trying to accomplish, is the ground swelling of mutual support among thousands of people, similar to JFK, people enthralled together something he couldn't accomplish in life, an envy, like the people celebrating the parade. Emotionally he's empty. His eyes tell it all.
