One day a red rose blossomed   in a forest. A pine tree  not far away said, "You're so beautiful! I wish I could be lovely like you. " The rose said, "I am the most beautiful plant in the forest. " Then the rose looked at a cactus  and said, "Look at that ugly plant. It is full of thorns  !"Sometimes, the red rose would look at the cactus and say, "This plant is useless. I'm sorry I am his neighbor. " Summer came and the plants and animals needed water, but no rain fell. One day the rose saw some birds stick their beaks  into the cactus and then fly away. The red rose asked what the birds were doing. The pine tree explained that the birds got water from the cactus. The pine tree told the red rose, "You can also drink from it. The birds can bring water to you if you ask the cactus for help. " The red rose felt _ , but she still asked the cactus for help. The cactus agreed kindly and the birds filled their beaks with water for the rose's roots. Later on, the rose never gave her opinion about anyone by look again. What does the writer want to tell us?
Look is not everything. Be careful of what you say to others. The red rose is more beautiful than the cactus. Don't feel bad about having an ugly neighbor.
