How do you handle an adult stepdaughter (aged 23) that still comes over to visit every second weekend like a younger child. She comes the Friday evening and stays until the Sunday evening. She works, but receives a very low salary. She''s overweight and has no boy friend. Her father overprotects her and she does not have to help with the household chores, because she''s " a guest"  . She rarely talks, chain smokes, looks depressed and unfriendly most of the time and glares at me when she gets a chance. I feel uncomfortable in my own house. I wish to say to her: go on a diet, lose some weight and get a life"  , but keep my mouth shut. I want to flee from the house, because I hate the atmosphere when she''s around. When I try to talk to her, she answers me bluntly. We don''t even take her to family gatherings, because she just sits there with her unfriendly face and stares at everyone. Her father holds himself blind to all of this. I can see she''s unhappy with her life, but why must my household be disrupted by this? It seems that she''s even more unhappy at her mother''s house, because she insists to come to visit us, but brings this negative vibe with her.
