Crap. I had a post all typed up, and then the board crashed.
Anyway.
Yes. it. does. Rather than lay it all out again, I may as well just tell you to re-read the posts I made last night. A huge part of how this impacts Natalie is the effect is has on her life outside of her family and home. It's like when Diana says to Dan, "so three women at work know I'm nuts?" (or whatever it is). Imagine what it must be like for Natalie to be known as the girl whose mother is a nutjob. To say that that line is irrelevant is to disregard that part of her story. If the thrust of the show is about what mental illness does to a family, and this is a family of people who function in the real world, then it also has to touch on those aspects of their lives. That's why we see Natalie at school. That's why we see Dan pick up the phone at work. Hell, that's why we see Diana shopping. It's about the family, yes, but their lives don't merely exist within that house and their own network.
And totally, disagreeing with you automatically = huge bitch! Notice, though, that it wasn't until YOU were rude first. Again. Just like the last time we did this dance. If you're going to give it, you'd better be able to take it. And if I get it, I'm going to give it back. Thankfully, though, I'm not the one who feels the need to resort to outbursts of obscenities.
