Tambu's Reaction to her New World

As I read on in Nervous Conditions, I looked forward to seeing what Tambu reaction would be to her new surroundings. Taking into consideration her reaction to Nyashu's standoffish-ness along with that of her brother's on his returns home, I thought that she would be quite picky in what she would choose to relish and appreciate. A good example of this is Tambu's reaction to Maiguru's description of the tea sieve as being undoubtedly necessary for a good cup of tea. Tambu takes the minimalist viewpoint, mostly because she knows she has gone through her life with no such commodity and has been drinking tea with no complaint. Her comment on comparing this new, thoroughly-strained tea to a cup when she returns home is indicative her awareness that it is quite possible that it is a lot better, though I don't think she thinks she will be repulsed. Also, regarding the shininess of the sink, Tambu catches a glimmer of the fact that her uncle's family actually isn't wealthy beyond imagination. She recognizes that the reason their sink isn't shiny is because they don't spend the extra money to buy the more expensive cleaning agents, thus they do have a certain amount of frugality which, in her mind, is good. The other thing which Tambu tells us is how she forced herself to refer to Babamakuru's house as just that - a house. She admits that had she written her reaction to the household at the time when she first encountered it, she would have used words of grandeur and amazement. Only through the lens of an older Tambu do we get the restrained reaction of the wealth that she will from then on continue to live amongst.
However, the point that stuck out to me most was Maiguru's behavior toward Babamukuru, and I am now interested to see how Tambu's opinion of her aunt might change as time goes on. Back at home, Tambu regarded her with immense awe and respect: "Maiguru was driven about in a car, looked well-kempt and fresh, clean all the time. She was altogether a different kind of woman from my mother." (p. 16) Then in Babamakuru's home, Maiguru is beyond submissive and only wants to appease her husband (my opinion only, as far as I have read we have no bad opinion of Maiguru from Tambu yet). "No, no, my Daddy-dear... Help yourself, my Daddy-pie!... Are you sure you've had enough meat, my Daddy-d?" Seeing how subservient Maiguru is to her husband, I wonder if Tambu will judge that negatively or accept it as normal/expected.
