why???

sometimes i wonder.....
y can only birds fly?
y do they have wings......why not me?
why can't i spread my wings and fly away.....
just walk alone a path and sway.....
why can't i walk on water??
why can't i do everything just later....?
why can't i wipe everyone's tear?
why can't i stop the injustice done to people?
why can't i stop the injustice done to me?
why do people say 'ME'...and why not 'WE'???
why do people try to be iconoclastic?
why today peoples' emotions are turning into plastic?
why is life so monotonous?
why is it not always good to be boisterous?
why has life become so insipid?
why is it necessary to take everything in good spirit?
why people kill each other?
why do they hate each other so much?
why can't i spread love and peace all over?
why can't i make some difference in this world??
why......???
