answer: #Person1# and #Person2# talk about the difference of spellings, pronunciation and meanings between British English and American English, but they think it does not influence their understanding.
documents: #Person1#: British English and American English are really about the same, aren't they?
  #Person2#: I don't think so. It seems that some of the spellings are different.
  #Person1#: You're right, Nina. Words like 'theater' and 'center' end in 'r-e' in England instead of in' e-r' like we spell them. Can you think of any more exampies?
  #Person2#: The word 'color'?
  #Person1#: Good. Actually, many words which end in 'o-r' in American English are spelled 'o-u-r' in British English.
  #Person2#: OK. There are some differences in pronunciation and meaning.
  #Person1#: Anyway, we both agree that British English and American English are different. Right?
  #Person2#: Sure. But not so different that it prevents us from understanding each other.
  #Person1#: Yes. I quite agree with you.
