answer: #Person1# suggests setting the bar picnic by the lake, but #Person2# thinks they should have it under trees to block the sun.
documents: #Person1#: Where should we set a bar picnic? By the lake? It looks so blue and clear, just like the Sky.
  #Person2#: I know, but it's hot today. Let's have the picnic under the trees over there instead of by the lake. The trees will keep the sun off us so it won't be as hot.
  #Person1#: Good idea. It's a sunny day for a picnic in the park but I wouldn't want to be running around too much.
  #Person2#: You're right. I take my dog for a walk on the walking path here to get some exercise, but only when it's cooler outside.
