yes, we all have our own dream, most of time parents can not understand our thoughts, but that is not means you should quarrel with them, You can try to comunicate with them, tell them your thoughts with patiences. and you will find they actually will support you nor disagree with you, and you also should listern to their advices, after all they have more society experiences, they just do not want you to make some wrong in you life. they just want to be good for you, i also quarrelled with them sometimes, but when i grow up, i find their real heart. we also should think about their heart.
