One day there was a ant who met a butterfly. The ant asked her if she liked him. She asked him, "Why would a beautiful person like me like a ugly thing like you?" Look at you said the butterfly. "You have to walk on legs while I get to fly with my beautiful wings." The ant didn't like the way butterfly kept bragging so he stopped being her friend. He became friends with other ants that were nice! 
Never brag because then nobody would want to be your friend.
