Yeah , everything except for the last is a lie . <| sep |> That might be the case but since the enneagram is trying to tell us the root of our behavior anger , fear , or shame , it can be pretty limited . Not many people can relate because the why is so much more elusive . MBTI just tells us the results of our behavior and not the cause , which is why I think it can be more relatable to people . You can find people of the same temperament but have completely different values . I think this is also why the enneagram is used in conjunction with MBTI . <| sep |> Each family is different and each person will have different values . This question really ends up being what YOU want . To be perfectly honest , this is your home . You can charge money to who ever you wish within reason . If one child is struggling , you dont have charge them anything if you do not want to . If another child is making lots of money , but trying to save up for their own place , it is still up to you . If one just seems to be complacent then charge them some rent . Some other things to take into consideration is if they provide other services such as buying groceries , paying certain bills , or just provide you with transportation . Again , it really depends on you and your family ' s values and relationship .
