Maybe you can understand that your parents like me, are motivated to equip our children to enjoy the challenges and opportunities of life, rather than endure them in pain, loneliness, costly errors, and fatigue. Believe it or not, our life experience is relevant, even if uncool.
I don't think that she has said anything to the contrary, has she?
Now I know that I am clearly biased, but, I do believe that Sam deserves at least a little more respect than that. And, I can't help but feel that you are projecting your own outdated views and your recent experiences with your son, unfairly upon her.
Sam is a fiercely independent woman and I am proud of how she has adapted to the move interstate and the challenges that she has been presented with in that time. Despite the move, the relationship with her parents is still strong; if not moreso because of it. By no means does she fall under the (usually exaggerated) stereotypical description that many like to use for those of her age.
And, yes, I'm well aware that she does not need me to speak for her. But, I would be appreciative if you could judge her on more than just her age and her gender.
