answer: #Person1# and #Person2# are talking about what birds eat.
documents: #Person1#: Those birds love my yard. See? They are probably looking for worms.
  #Person2#: Yeah, they are lucky they can find meals in lots of places. We have to go to the grocery store to buy our food.
  #Person1#: True, but I wouldn't want to eat what they do, even if it's free.
