The moral of the story is "Steping back sometimes is the best way for going forward". A white  sheep and black goat live on the two banks of a river and they are friends. One day, both of them get emergencies coming up and need to cross the river immediately and they bump across on the only bridge. Pushing and shoving on the bridge, none of these two is willing to give the way to another, until they both fall into the river. Then, they get themselves in a worse trouble.
