As Foob shows, this is not the case. It has always seemed to me that Elly's real best friend has never been Connie Poirier. Instead, her truest friend is a translucent cartoon ghost with the name "Ida Know" stenciled on her chest. As by way of example, let's remind ourselves of when Liz got playing with that bag of milk and unintentionally broke it. We know that Lizzie felt as if she might as well run off because Mommy was sure to throw her out anyway. Should someone have asked Elly why her child is afraid of her rages, the response would quite probably be "I don't know." This is because of something Bil never thought of: an adult lacking in self-awareness. He could live in a world of children pretending that they didn't know but not a world where supposedly grown people were unaware of why things happened and how they affected the world around them.
This means that his belief that people were honest about how their actions affected those around them was also overly generous. This is because he could probably watch John make boneheaded mistake after boneheaded mistake as a husband and father and claim that its' not his fault that his wife feels frustrated or that his children think of him as an ogre when everyone knows he's a really cool guy and assume that he's just saving face. He refused to live in a world where a grown man could say that it must be Not Me's fault that Elly thought of John as a chauvinistic pork-butt or that his kids thought of him as being a short-tempered loon who can't take what he dishes out.
