Ron Flowerdew's Links
He believes Randy to be an idiotic kid that is just simply a mess, and thinks that his lack of talent is a shame to their family. Growing up, he found Randy annoying, and added to Randy's lisp, felt embarrassment. Overall, he just feels a watered down disdain for Randy. Fortunately, he lives far enough that he doesn't have to feel embarrassed for him very often.
He's very insecure about himself, and is worried that maybe his oldest brother is embarrassed to be around a dope like him. After he's heavier, he starts to worry that now there's another thing to add to the list of pitiful things about him, and tries to avoid him so he doesn't have to have Ron be disappointed with him. He wants to be able to impress him, but knows that he's so pathetic, he may never will. He knows that Ron looks down at him, and it just adds to his insecurities and feelings of uselessness.
That being said, he loves playing with his nieces and nephews.
