So I have a sister that wont talk to her father or family members. What do i do?
well i would remind her of good memories and the complements ur parents said about her and i just find if you bring them up and good things that happen ur sister will want to have those memories again
is it because she is just not into talking to people or is she mad about something?
Hmmm. How close are you to this sister? If you are close to her then try and talk to her. Love her and tell her all the great things about your family if that fails bring in her mother and father have them talk to her and maybe get her a counselor.
The one who doesn't respect her father, mother or family members will never be good and loyal to you. Leave her alone isolated.
Ask her and if she doesn't tell you what's wrong try to develop a relationship where you both share your feelings with each other
