This is the best bit. It's everything I've told this empty fuck and which he fervently denies. Ralph dates highschooler because he's still mentally 18. When Faith grows older than that, she'll be to old for him emotionally, just like Nora, just like Ade.
There's nothing sadder than the man who can't get over his highschool years. Ralph will forever be the uncle in Napoleon Dynamite throwing the football at the camera. Back in college, he could have thrown the ol' pigskin clear over the mountains, he could have gone pro.
