Dear Li Ming,  This week we learned about some interesting animals. I used to think only the same animals live together. But yesterday I learned that sometimes different animals live together. Do you know about the rhino? It is big and strong. But it always lets a small bird, an egret, sit on its back. Are they having fun together? Maybe, but mainly they are helping each other. The egret helps the rhino stay healthy by cleaning its skin. It also makes noise to warn the rhino about coming danger. The rhino helps the egret get food easily. How? It scares small insects hiding in the grass, and the egret eats them. Isn’t that interesting? Danny
