You're grouping anger, deceit, cynicism, selfishness, joy, despair, hate, vengefulness under "whining". I guess that must make sense to you somehow.
Indeed...
So nonsensical take of George, who is the core of the whole frigging Seinfeld sitcom. The series wouldnt be two notches above most sitcoms if it wasnt for that character.
Like, when he was stressing on those who occupied the pay phone in the chinese restuarant, was he just whining? A pay phone he urgently wanted to use to call his girlfriend, who he left hanging abruptly while into foreplay...because while kissing here he suddenly wanted to take a dump, but fretted over he cant do it at her apartment because his somehow he thought his world would crumble if she smelled the aftermaths of it. So he decided its more suitful for now to just leave her and run away in the middle of foreplay.
The kind of complex show of reactions and emotions in one simple episode like that, shows how he REALLY isnt someone to chalk down under just whining. Exaggerated for emphasize at times, but he is by far one of the most authentic and quite real of characters.
