Once near a pond was a very big tree. There lived a big group of swans. In that group lived an old swan who was very wise, intelligent and far-sighted. Everyone around respected him. One day, old swan saw a small vine wrapped at the bottom of tree trunk. He called other swans and said, "We should destroy this vine or one day it will take us to our death."Everyone laughed and said, "How can this little vine hurt us??"Old swan explained, "Today, it seems little but with time it will become thick and strong and will be wrapped up all around tree trunk and would be so thick that hunter could climb on tree using this vine as stairs.."Other swan could believe and said, "But it's so small, how can this small vine form a ladder?"One of them said, "You are worrying too much.. this small vine can not harm us ever..". Other said, "You are just now making up stories to prove that whatever you say is right..!!"Saying this everyone ignored his warning and kept on enjoying life. Time went by and soon that small vine climbed up to branches of trees. With time vine became strong and thick wrapped around trees and formed kind of stairs which could be climbed very easily. Soon, swans noticed that vine and realized they should have listened to old swan as nothing could be done now because that vines became so thick that it couldn't be destroyed by swans. One day when all swans were gone in search of food. A hunter passing by, saw that tree and climbed up. He placed a net trap below tree and left. When swans returned they got stuck in that net and started fluttering there wings trying to get out of that trap but they were stuck and couldn't get out. Everyone was ashamed and felt guilty for not listening to wise old swan. They were so ashamed that they couldn't gather courage to ask him for help now. Just then one of those swan said, "We were fools, we didn't listen to you but please help us.. only you can help us.. please tell us a way by which we can get out of this trouble.. we will follow your advice and do as you say."Old swan replied, "Ok then listen to me carefully.. in morning when hunter come to check his net.. you all pretend to be dead. thinking that you are dead, he will start to get you out of net and keep on ground.even then you all should stay there like dead and as soon as he keeps last swan on ground I will whistle and you all should fly away that instant.."Everyone understood. Next morning when hunter came, he did same as said by old swan. Thinking of those swan dead he kept all of them on ground and as soon as old swan whistle, they all flew away. 
The advice of wise people should be taken seriously.
