I think that the aspect of "people watching" alluded to in the last post helps to explore much of what Miss Brill enjoyed the most. She revels in the construction of an alternate identity to her own. This identity is steeped in how she carries herself on Sundays, in the park and in the cafe. It is an identity where she is able to be more than what she is in her own existence. I think that this is what she enjoys the most. The elation that describes how she exists when Sundays roll around is what she takes the most pride in and within what she takes the most amount of pride. When the two lovers criticize her, she blames the stole, which might be a reflection of how much pride and happiness she has in her Sundays. She is not able to take the blame herself because of the joy she experiences, which is why she has to blame something else for what others say about her.
I think Miss Brill enjoyed the cumulative effects of her Sunday outings the most, she enjoyed life on those days. She looked forward to the "season", the leaves were changing colors and the band always played on Sundays. Part of her outings were getting dressed, she talked to her wrap. She enjoyed "people watching", she made comments about the old couple, the man with the funny moustache, and the woman who had turned grey (hair once was yellow). She considered herself an expert at listening to peoples conversations and drawing conclusions from them. She enjoyed making observations about other's behaviors, when the lady dropped her flowers and the boy picked them up for her, then the lady threw them away. Miss Brill thought that was rude. She liked the enormity of it all, she enjoyed life.
