i think we want to obey our parents when we chose a person to marry.bcoz that is a landmark of our life.we cant restart our life with an error if we marry an unmatching person.if so we have to suffer through out our life time.therefore we must get help and it is a must to be intelligent enough to understand the person who we are looking for or what type of person matching you..as a parents they have plenty of experience to understand and recognized who is he?so i supose the best marriage is arranged one. thank you.
