documents: #Person1#: Did you remember to bring the tennis balls?
  #Person2#: No, I didn't...
  #Person1#: What! I thought you said you'd bring some. How are we going to play without them?
  #Person2#: Well, the ones I had were very old and I know you'd only get cross if we played with them. So I phoned Janet. She's just bought some new tennis balls. She'll be along in a few minutes then well be able to play.
