There are ALWAYS good reasons to respect your parents.....you just have to make sure as you become an adult that you don't lose you individuality by being what you assume they want you to be.
I did that when I was younger and really made decisions I wouldn't have if I didn't think that's what my parents wanted me to do. When I mentioned it later in life....BOTH of my parents said I should've stood up for myself and not been such a ninny.
