are we the wisest

i sometims question the human race's claim to be the wisest-if we are the wisest then why this chaos in the world of rlaqtionships, i m not bothered about other spheres, but the rules of our civilised existense-social norms , values , are not leadind us to a life of harmony and peace,.take the cas of birds-they mate- make a nest-lay eggs- then feed their young ones and after a few days prepare their young ones to fly out of their nest, out of their wings, out of their protection.that's that. they miss their young ones but donot ask for anything in return from the young ones.but we the human-being refuse to let go of our children, we emotionally blackmail them for having taken good care of them, for having providing thm good education and spending a large chunk of our earning on them. when their time to fly away comes w chain them to lookafter us,if we allow them to go far away from us we never forget to repeatedly remind them that how much we miss them,i mean what of the poor kid-- he cant enjoy the youthful tims without secretly having a load of guilt in his heart.
