documents: #Person1#: I want to keep a pet, but I don't know which one to buy?
  #Person2#: Dogs are nice, but they are really energetic, and you need to make sure they get enough exercise every day.
  #Person1#: Having a dog would probably be too much work for me, then.
  #Person2#: What about cats? They are more independent.
  #Person1#: Actually, I was thinking of something a little more exotic. I don't want a common pet like a dog or a cat.
  #Person2#: How about a lizard? Are lizards more along the lines of what you were thinking of getting?
  #Person1#: Yeah, are they easy to look after?
  #Person2#: Yeah, they are pretty low-maintenance ; they eat almost anything.
