A family friend told me that when her husband died, she put all his clothes in the spare bathroom and did not go in for two years. Her husband's death was expected (he was elderly and had dementia - my family friend is in her late 80s), and she said she thought she was prepared but she wasn't. She is a retired nurse so she's seen a lot of death and she was initially very "he had a good long life, death is a part of life" approach, but when she began to grieve it hit her differently.
I can certainly understand Maggie not going anywhere, and that seems to be the family gathering place but that house is huge.
I used to work at a company that had six business unit and each business unit functioned pretty independently. I was in marketing and each business unit had its own marketing team. (The company later got a new marketing VP who re-organized everything and centralized it by function, so there was a market research team that worked across all business units, a PR team that worked across all units, a digital marketing team, etc.) If Zoey's company is organized into ... people who work on the watch (I think that's the only thing I've heard them talk about!) and people who work on ... other stuff, I can see it.
An ex of mine is an ad guy and he would tell stories about clients being like "I don't like it" with no further comment. They'd have to ask a lot of follow-up questions. I did a brief stint on the agency side of things and it can be very frustrating (although IMO a micro-managing client is worse).
It reminded me of Crazy Ex-Girlfriend - they eventually showed us what the musical interludes looked like on the outside and it was Rebecca staring exaggeratedly weirdly into space.
