Seems like Doug is, has been, and always will be a miserable person; a victim of his own negativity.
He's mainly a victim of the 10-12 ounces of cerebral tissue scooped out by a neurosurgeon and tossed,
splat, into a hospital wastebasket.
Along with piano lessons and concern for personal appearance, that discarded gooey mass included personality, judgment, and every redeeming quality he may once have had.
