The different between "the boy" and "the girl"

Sometimes i feel a little bit envy with the boys,because the boys can go out from hous up 9 pm and the girls can't.the boys can keep the secreet when their friends tell something to the boys and the girls can't.the boys can riding the motorcycle everytime everywhere they want to go and the girls can't.the boys can go out when the class start and the girls can't.many question in my mind why the boys can feel freedom like this.i dont know why and who knows ?but the boys had a job job that is darting through the heavy "responsibility"
