W: Hello! Glad to see you here!
M: Me, too. How are you going these days?
W: I’m OK. What are you doing in the library?
M: Oh, recently I’m curious about British English and American English. So I just come here to get some information. They are really about the same, aren’t they?
W: I don’t think so. It seems to me that some of the spellings are different.
M: Such as?
W: Words like theater and center end in "r-e" in England instead of "e-r" like we spell them.
M: Can you think of any more examples?
W: The word "color" is another case in point. In fact, many words which end in "o-r" in American English are spelled "o-u-r" in British English.
M: I’m still not convinced.[23]I mean, if someone comes here from England, we can all understand what he’s saying. The spelling doesn’t really matter that much.
W: We’re not just talking about spelling.[24]There are differences in pronunciation and meaning too. I remember seeing an English movie where the actors kept calling their apartment a flat. Half of the movie was over before I realized what they were talking about.
M: So there are slight differences in spelling and some vocabulary.
W: And in pronunciation, too. You aren’t going to tell me that you sound like James Simpson.
M: James Simpson isn’t English. He’s Scottish.
W: Okay. Anyway, the pronunciation is different.
M: So British English and American English are different in many ways, right?
W: Yes, sure.
M:[25]But it’s not so different that it prevents us from understanding each other.
W: That’s exactly what I mean.
