I know Kate has a lot going on, but when her neighbor first confronted her about the car on the sidewalk, he had his cane, so it wasn't hard to figure out why he was upset. To me it was another example of Kate being all about herself and her problems.
The scene at the restaurant was so contrived. I'm in the tech industry, and would find it extremely unprofessional if a sales executive brought their spouse to a work dinner. Sales dinners are meant to woo clients, so you bring along someone like a solutions consultant or account manager to show the client that they will be in good hands after they sign the deal. And you can't tell me that Kate's self-pitying presence is so charming that it makes people buy database solutions.
When Kevin was going on and on about turning down movies and "jowl city", I was wondering if it's acceptable to mock someone in an AA meeting. Then Cassidy and Nicky started laughing and the meeting leader admonished them, so I guess it's not acceptable.
The kid Big Three story was centered around Randall and Kevin, but there was a throwaway moment when Kate hopped on the scale after doing the workout video with Rebecca, and her face crumpled, that broke my heart. It's such a kid thing to think that if you do something to lose weight you will see instant results.
