The reason that I mention this is that people like that can't tolerate competing narratives at all well. As I've mentioned once or twice, I come from a family of people just as bull-headed, contrary-minded and short-tempered as Elly is and have had a lot of practice dealing with people who can't handle conflict because they see it as an attack on themselves. Next week's arc is a very annoying one because it's a prime example of this tendency to turn the conversation into a monologue about herself. We get to plow head-first into a scenario where Mike and Lizzie's wanting to participate in extra-curricular activities like the other kids becomes a monologue on how it keeps Elly from living her life the way she wants to. It's not about Mike having a social life and bonding with friends, it's about how Elly has to run around serving him like she's his SLAVE instead of the mother who's supposed to be the only person who decides what he does, where he does it and when.
It's this need to see anything her children say or do that makes her feel uncomfortable or angry as a cruel and vicious attack on her person inspired by a malicious need to silence her that tended to keep Liz and April from talking to her about their lives. Why say anything if all anyone's going to get is blathering about how bad children are, a stream of absurdity that shows how out of touch and proud of it she is or a torrent of consciousness rant that makes everything about Mom? This differentiates them from Mike who doesn't see that he's supposed to talk to adults at all because that's stooling to the guards.
