I really liked this. Of course I liked that they went to visit Monica and I like how they got to finally re-integrate into the real world. And very happy that they got William back.
I think what your story offers that is so rare is a portrait of what their lives should be like, could be like, if there wasn't always an impending wolf at the door, as you say. It's beautiful in its description of simple joys that most people might take for granted, that they are almost priveleged to receive.
