answer: #Person1# gives #Person2# some suggestions about painting a sky because #Person1#'s father is an artist.
documents: #Person1#: Hey, Jane. It's a lovely painting.
  #Person2#: Thanks, Mark. But it doesn't look right to me. You know, I'm just learning.
  #Person1#: Let me see. I think it might be the color of the sky.
  #Person2#: Why? The sky is blue, isn't it?
  #Person1#: Well, that depends. I mean the sunset can be full of reds and purples.
  #Person2#: Oh, yeah. That's the point.
  #Person1#: By adding some other colors to the sky, you'll get a more natural picture.
  #Person2#: I'll try that. How do you know so much about painting? Taking some courses?
  #Person1#: No, actually, my father is an artist. He told me a lot about painting, and took me to different exhibitions.
  #Person2#: Ah, I see. I hope I can meet him some day.
  #Person1#: That could be arranged. Er ... it's three now, how about a cup of coffee?
  #Person2#: I'd love to.
