LEARN TO FIX YOUR LOYALITY
Once there broke a war between the birds and the beasts. Many battles were fought one after the other. If vow the birds got the upper hand, the next time beasts were successful.
The bats played a very treacherous role in this war. They sided with whichever side got the better of the other. Thus they were changing their loyalty from side to side.
Neither side paid any attention to the bats till the war lasted. But when the war got over, the bats didn't know which side to go. First, they went to the birds. But the birds refused to own them as many birds had seen them fighting for the beasts.
Then, the bats went to the beasts. But there also they faced the same situation.
So, they were left all alone because of their disloyalty.
