A: Mom, are there animals in the forest?
B: Yes, there are many different kinds.
A: Then why haven't we seen any?
B: They are probably hiding.
A: Why are they hiding?
B: Animals are afraid of people.
A: Maybe if we hold still, they will come out.
B: Why is that?
A: They will think we are trees.
B: I think they will know we're not trees.
A: Can we try it and see?
B: No, dear. Let's keep walking.
