Great analysis. The childish mentality is one thing but it really probably goes deeper than that. It's the equivalent of asking your crush on a date, being rejected, then pulling out your Mr. Roger's trunk of hats, mustaches, and other thinly veiled disguises and continuing to pursue your lost cause half-assedly disguised as someone else, even though your true identity is apparent. Seems odd for an adult to be so obsessed with being a childlike burden, but we are all best off to ignore.
