answer: Mr. Cooper encourages #Person1# by praising #Person1#'s painting and tells #Person1# the most beautiful things result from artistic accidents
documents: #Person1#: Mr. Cooper! I tried to make my own colors based on what you taught us in class yesterday. It wasn't easy, though.
  #Person1#: Can you see it here? I wanted to make purple, but I didn't use quite enough blue. It turned out just kind of gray and boring.
  #Person2#: Well, I think it turned out great anyway! This is part of the fun of painting - discovering what you can do with a little imagination, taking some risks, and trying to do new things.
  #Person1#: Thanks for the encouragement.
  #Person2#: Sometimes the most beautiful things result from artistic accidents. And I'd say the same is true of almost all interesting things.
