Y’know, it’s a shame that we never got to see an actual interaction between Fred and his wife in the Discworld books. I mean, we *hear* about them interacting and get an idea of what their relationship is like from that, and I also understand it’s a part of the joke about them being so busy they communicate through notes they leave for each other, but still. We don’t even learn the woman’s first name.
Yet, despite this I’ve managed to piece together what little information we’re get about her throughout the Watch books to get a general idea about what she’s like and what she does that keeps her so busy all the time. So, let’s review what we do know for sure about this woman of mystery.
She has a job that keeps her extremely busy.
She’s been doing said job for at least as long as she’s been married to Fred.
She is one of the few people that will directly call out Sergeant Colon when he’s being an idiot.
She and Fred have kids and grandchildren.
She seems to enjoy interior decorating.
She most likely has known Sam since he joined the Watch and Nobby since he was a kid. Also, at this point it’s fair to assume she’s met the other important watchmen as well. (Carrot, Angua, Detritus, Cheery, etc.)
Personality-wise, I’d say she’s a nice but a very no nonsense type of person. Patient, but only to a certain point. Very hard worker and tends to get absorbed in her job. She obviously loves her husband, but she can get easily exasperated with him. Her feelings about him are probably best summed up with something like: He’s an idiot, but he’s my idiot.
As far as her work goes, I think she’s either an antique dealer or an interior designer. This is because an interesting little detail I picked up on in Jingo. Fred brings her back souvenirs (which is really sweet tbh) and they’re furniture/decorating stuff. Plus it’s mentioned in the books that’s she often asks Fred’s help decorating their house and moving furniture. So if she’s an interior designer, she might sometimes keep some of the furniture she uses for her clients there, and if she’s and antique dealer she might run her business from their house. After all owning a proper shop is expensive and Ankh-Morpork is low on space.
