We must differentiate here between two things: being kind to parents and total obedience to them. Obedience must be discriminating. We obey our parents only in what is right and what is calculated to please Allah. But we should be kind to them in all situations. Elaborating on this issue, we’d like to cite for you the following fatwa:
“The first point that I would like to make is that every son and daughter is required to be kind to his or her parents and to ensure that their wishes are properly observed or complied with, as far as that is practical, useful or beneficial. Whatever a son or a daughter can do to please his or her parents, he or she should do, provided that it does not involve any disobedience to Allah or injustice to other people.
almighty Allah has emphasized that kindness to parents is one of the most important qualities of believers. He says in the Qur’an: “Thy Lord hath decreed, that ye worship none save Him, and (that ye show) kindness to parents. If one of them or both of them to attain old age with thee, say not ‘Fie’ unto them nor repulse them, but speak unto them a gracious word. And lower unto them the wing of s
ubmission through mercy, and say: My Lord! Have mercy on them both as they did care for me when I was little.” (Al-Isra’: 23-24).
Kindness to parents is mentioned as a duty of believers several times in the Qur’an. There are many Hadiths that encourage us to be very kind to our parents. However, such kindness does not require a son or a daughter to obey his or her parents in whatever they may require of him or her. Suppose that a father asks his son to tell a lie, give false testimony, or drink or do something forbidden. If the son complies with his father’s wish, then he commits a sin that will not be less grave simply because he is carrying out his father’s orders. The Prophet (peace and blessings be upon him) said: “No creature may be obeyed in what constitutes disobedience to the Creator.” That applies even in simple matters. Suppose a father arrives from abroad, having bought a bottle of some expensive alcoholic drink and he asks his son to deliver it to a friend or a neighbor. If his son complies with his wishes and simply takes the bottle to the person concerned, he commits a sin, because carrying an intoxicating drink to someone who will drink it is forbidden. Children must refuse to obey his/her father in such a situation.
Parents are also responsible for what they demand of their children. It is not right of a father to require his son or daughter to do something that is contrary to Islamic principles, relying on the fact that his son or daughter should obey him. Indeed, if the father does that, he fails in his duty to help his children choose only what Islam approves. Not only so, but he forfeits his rights to be obeyed by his children. We must differentiate here between two things. Being kind to parents and total obedience to them. Obedience must be discriminating. We obey our parents only in what is right and what is calculated to please Allah. But we should be kind to them in all situations. Allah Almighty says that if parents try hard to persuade their son to associate partners with Allah, then he must not obey them, but he should “… bear them company in this world’s life with kindness.” (Luqman: 115). When the Prophet (peace and blessings be upon him) was told by one of his female Companions that her mother, a non-believer, had come to visit her, he told her: “Be kind to your mother.”
Such kindness may not go as far as disobeying Allah for a parent’s sake.” Excerpted, with slight modifications from:

Having clarified the above, it becomes clear that every child should be kind towards his/her parents in all situations. Being obedient to parents does not include obeying them in haram or preventing him from discussing serious issues with his parents and to express his opinion and even abide by it as long as the discussion is done in a good atmosphere while respecting the feelings of parents and being kind to them. May Allah help you be obedient to your parents and to grant you happiness in this worldly life and in the Hereafter.
