It does seem strange to me that when I initially looked at this comic, it didn't seem "funny" or abnormal to me. Doesn't everyone have a running narritive of their life going in their head all the time?
Don't you sometimes verbalize it when no one else is around? Or even sometimes when there are people around?
I think one of the signs of a truly creative and gifted individual is the ability to refer to one's self in the third person and not have it sound stupid or annoying. Not like when Trump calls himself "The Donald." Thats just dumb.
