I actually had to tutor a pair of kids from a family like this. They both independently confided in me that they hated their parents, especially their mother, and could not wait to move out and get away from her. The older of the two actually said that his wish was that she would die alone and unloved in a nursing home, with none of her children in attendance.
And that was before she found him with an e-cig and threatened to call the cops on him as her opening move, and he was 20 at the time.
