I have been reading of Emma's thoughtlessly insulting 'clever' remark at Miss Bates expense at Box Hill, and its aftermath. After Mr Knightley's reproaches her contrition is real and lasting, and she goes early the next day to Miss Bates to make amends.

Miss Bates shows no sign of bearing a grudge, and is her usual chatty self so that it is not easy for Emma to get a word in edgeways. All the same, I am surprised that Emma does not refer to her offence at Box Hill and make a clear formal aplogy to Miss Bates.

I think an outright apology would have been appropriate, given the circumstances. Perhaps it might have embarassed Miss Bates a little (and also Emma), but I think it would have been well-taken and restored Miss Bates self respect.
