The whole story was over.I thought about the story for a long time,in real life,every one of the four characters in the story would be found.For most of us,did not want to see the change and did not even want to deal with it.We did like neither Scurry nor Sniff.I thought i was more like Hem,when the surroundings were changed,i would thought it over, changed my view,then did it.But when i met difficulties,i would strugle with myself and insisted on doing it.
