she is fixated on watching tv (to the point of not interacting with people very often) and criticising dad almost every moment! she has a VERY low tolerance for frustration if anyone says anything she doesn't like or agree with and seems to use temper tantrums to control the situation. dad's coping mechanism is to not rock the boat & always let her be- no matter how cruel or unreasonable she's being. i worry that both of them are experiencing a poor quality of life. help.
