answer: #Person2# tells #Person1# #Person2# met Bill through a computer bulletin board on the network. Then #Person2# teaches #Person1# how to chat in that way.
documents: #Person1#: How did you meet Bill?
  #Person2#: I met him through a computer bulletin board on the network.
  #Person1#: Oh, really? Which bulletin board?
  #Person2#: It was the one I used down at the local coffee house called the San Francisco Net. It has been around since 2016.
  #Person1#: I've heard about that, but I've never tried it.
  #Person2#: You ought to. Fifty cents buys you an hour of computer time. A 'Chat Session' links you with people in other cafs. We can make new friends by that means.
  #Person1#: But I don't like to talk on the network with strangers.
  #Person2#: You can do that. A private room lets you talk alone.
  #Person1#: OK. I'll try it.
