that is true, my father has traditional Chinese ideologies, he probably expect me to reproduce. you can call me weird, but ever since I was 4 years old, i had this notion that i would not get marry or reproduce. no homo, but again other people think otherwise due to their narrow-mindedness.
as a new parents, I guess I would understand what your parents expect.
Having kid or not is one thing. But I do vote for getting married if the right person appears. Having a companion is just better than not having one, IMO.
Parents can expect a lot of their grown-up children but it doesn't mean you have obligations to satisfy all of their expectations. Good parents let their adult children plan their own lives. They give sensible opinions, not straight orders. Bottom line, follow your heart and your head but don't do anything stupid.
