answer: To get to the conference centre early, #Person1# and #Person2# decide to take the underground, and #Person2# proposes to go there together.
documents: #Person1#: Mister Ewing said we should show up at the conference center at 4 o'clock, right?
  #Person2#: Yes, he specially asked us not to be late. Some of the people from our East York branch office are coming and he wants to make a good impression on them. How are you getting there?
  #Person1#: I was thinking of taking my car but I think I'm just going to take the underground because there is construction on the highway. What about you?
  #Person2#: I'll be taking the underground as well. Why don't we go together? I've been to the conference center only once, and I'm not sure if I can find my way around there.
