a lot of them will develop mental health issues and think too highly of themselves
you respect them because they're done contributing to society. They've lived long and honest working lives and helped build the social fabric you rely upon to get yourself started in life. You respect their opinions because they've lived longer than you and know more about the world than you, but you don't let them control you. You give them an extra little bit of patience for their stubbornness and continue living your life while also holding a lower standard for their behavior.
