One day the seagull was very, very, very hungry. The seagull saw a big fish in the sea in the eagle's area. The seagull wanted to eat the big fish, but it was very heavy. Then an eagle saw what the seagull was trying to do. Seagull might die because the weight was too much and would prevent the seagull from flying away. Eagle did not do anything even though seagull ate fish in eagle's area. The seagull is not bird that hunts in the sea. Seagulls are bird that hunt in the sky. Then the eagle ate the seagull. 
Everyone should care about their own things.
