Eddie's demands for $50 for a new video game is what drove Louis to decide that he needed to be as strict to Eddie as Grandpa was on him. Louis then keeps making hyperboles that Grandpa had 3 kids at Eddie's age, his ear melted off, he sold bread hot enough to give him third-degree burns and he only got an egg for his birthday before later on stating "As I say that I realize I'm exaggerating, but it could have happened".
His surviving wife Jenny does not miss him, at least not entirely. Jenny then told Louis to remember that despite Grandpa being a hard worker, he was still a cruel and unthankful man who wasn't very kind to others. This caused Louis to realize that being miserable and exhausted from work doesn't give you the right to lash out at people.
