... young master Wei, do you truly think all creatures ask the question 'why'?

[ Xunxian is now scratching the thick fur without hesitation. ]

The birds migrating to warmer places for the winter and then returning do not know the answer to 'why', they just do.

[ That doesn't mean that Xunxian has stopped asking, merely making sure that there are no hopes raised for an answer. His own curiosity is more along the lines of asking Anurr why a bear and not a person who can communicate with everyone, but he doesn't have much hope that that would get answered, either. ]
