Oh dear, I suppose we will have to agree to disagree, Jonathan. I would want to be friends with Emma. I could never deal with someone reserved like Jane, who I suspect holds secrets. And I certainly would want nothing to do with gabby, boastful Mrs. E., always needing a compliment.
How many mea culpas does Emma have to confess, for you to see she was genuinely sorry for the situation she caused with Harriet and Mr. Elton. She has vowed to not matchmake any more, and so far has kept her promise. Emma is a true friend to Harriet, and Mrs. E., has decided to make Harriet her target, since Emma has not accepted her invitation to play music.
pg. 494 In one respect Mrs. Elton grew even worse than she had appeared at first. Her feelings altered towards Emma. Offended, probably, by the little encouragement which her proposals of intimacy met with, she drew back, in her turn, and gradually became much more cold and distant; and though the effect was agreeable, the ill will which produced it was necessarily increasing Emma's dislike. Her manners, too__and Mr. Elton's __were unpleasant towards Harriet. They were sneering and negligent. Emma hoped it must rapidly work Harriet's cure; but the sensations which could prompt such behaviour sunk them both very much. It was not to be doubted poor Harriet's attachment had been an offering to conjugal unreserve, and her own share in the story, under colouring the least favorable to her, and the most soothing to him, had in all likelihood been given also. So was, of course, the object of their joint dislike. When they had nothing else to say, it must be always easy to being abusing Miss Woodhouse; and the enmity which they dared not show in open disrespect to her found a broader vent in contemptuous treatment of Harriet.
Emma feels bad because Harriet has not had anyone ask her to dance. Mrs. Weston tried to prompt Mr. Elton to ask Emma to dance and he refused. I can't even imagine WHY Mrs. Weston would ever consider it a good idea for Mr. Elton to ask Harriet to dance. Does she have no knowledge of all that transpired? Emma is mortified to see Mr. Elton be so blatantly disrespectful to Mrs. Weston. Emma cares very much for Harriet's feelings.
pg. 516 In another moment a happier sight caught her eye__Mr. Knightley leading Harriet to the set! Never had she been more surprised, seldom more delighted, that at that instant. She was all pleasure and gratitude, both for Harriet and herself, and longed to be thanking him; and though too distant for speech, her countenance said much, as soon as she could catch his eye again.
Even Frank does not like Mrs. Elton: pg. 514
"How do you like Mrs. Elton?" said Emma in a whisper.
"Not at all."
"You are ungrateful."
"Ungrateful! What do you mean?" Then changing from a frown to a smile, "No, do not tell me, I do not want to know what you mean. Where is my father? When are we to begin dancing?"
As we read on, Jane even gets infuriated with Mrs. E., butting into her business about getting a governess job.
I just do not see Emma as a snob. She truly does not like Mrs. Elton, and I can't say as I blame her. I am not allowing Emma to choose for me, who I will like in the story. If Emma were not even a character in the book, and all the characters were, I still would NOT like Mrs. Elton. She is very mean spirited, self centered, boastful, domineering, annoying and down right difficult to be in the same room with.
