What to make of this comment?
"The sight of Mrs. Clay in such favour, and of Anne so overlooked, was a perpetual provocation to her there; and vexed her as much when she was away, as a person in Bath who drinks the water, gets all the new publications, and has a very large acquaintance, has time to be vexed."
Sounds like the narrator knocking Lady Russell a bit. She's "vexed" but easily distracted. Or perhaps she's so used to seeing Anne treated thus that she's become somewhat inured to it, especially when there are so many diversions at hand.
