Which of the following is NOT an evidence of some people’s carelessness in daily communication?

M: Some people are terribly careless in the way they speak, don’t you think, Lucy?
W: In what way do you mean, Bill?
M: Well, in every way. In pronunciation, in the words they use, and even in their grammar.
W: You mean when somebody says, I ain’t never seen nothing like it or something like that?
M: Oh no, I don’t mean that sort of thing at all. You’d expect to hear a badly- educated person say that. No, I’m talking about ordinary people like you and me, people who’re supposed to be well educated, in fact.
W: Can you give me a ...
M: An example? Certainly. Let me see. Yes. Suppose I’m about to leave somebody after a meeting. He might say to me "Where are you going to?" Perhaps with the idea of giving me a lift in his car.
W: Well?
M: Well, that’s just what I mean: "Where are you going to? Why doesn’t he just say? Where are you going?" It’s quite unnecessary and incorrect to add "to".
W: Oh, so that’s the kind of thing that bothers you! That’s no big deal.
M: Well, all I know is that English is going to the dogs, and as far as I can see, people like you are doing nothing to stop it.
