answer: #Person1# offers to pick up #Person2# after the concert, but #Person2# prefers catching the train considering the traffic.
documents: #Person1#: Shall I pick you up then?
  #Person2#: I don't know. The traffic will be really bad at that time. You know what it's like after a concert. I was thinking of catching the train.
  #Person1#: Hmm...It will be late. Won't that be a bit dangerous? I'm not busy you know.
  #Person2#: That's really kind of you. I've also thought of getting a taxi, but then there's still the traffic to worry about. I think my original idea is the best.
