The best way I can see is don't tell them anything about your life that you don't ABSOLUTELY need to share. Think of them as annoying coworkers and not parents. They don't need to see you struggle or see your hurt. They don't need to know how you are doing financially, in school, or in life. They don't need to know anything except the absolute basics. That's how I deal with my own family. I go to other people for support, comfort, advice, or to vent.
