Was any of the townspeople invited? Not sure either. IMO, based on other my readings on the English society over the years, he HAD to had been invited because he was a member of the village and one of the more wealthier ones too. The wedding was more than likely sponsored by the Woodhouses, and so, being the proper English that the Woodhouses were, they would have no choice but to include him in the invitation along with the rest of the townsfolk. Are the Woodhouses going to risk losing his friendship and social connections by not inviting him? I hardly think so. That's why I think it was he that decided not to attend because Miss Taylor didn't affect him one way or the other.
I'll say very good guess. I'm not sure what it really is. But I was very surprised that he was not at the wedding.
I'm also surprised that they made no mention of them being sorry that Mr. Knightley could not attend the wedding. Also, Mr. Knightley didn't express his feelings about not making it.
Now, why is half a mile away to Randalls a problem for Mr. Woodhouse and Emma? That's where Ms. Taylor has gone to. And yet Mr. Woodhouse seems reluctant to visit her. He does say that the distance is quite far and that he can't possibly walk it. But I think it's not the distance that causes his reluctance. It must be something else. What do you think that might be?
