Mabel — A True Shut-in

Riddle: In the home where Mabel resides, she has a reputation for walking very slowly, even though she is only 40 years old. Her slowness doesn't appear to be related to arthritis or to other medical ailments, but is more likely due to heredity, as her parents both had the same condition. Mabel does not use a walker or a cane to move about, and a wheelchair would be out of the question. Mabel is an extreme introvert who basically stays in her home 24 hours a day, 7 days a week. Although it sounds a bit strange, you could say, even when Mabel leaves her home --- she stays at home. Although she frequently leaves the front door to her home open, she is easily frightened, causing her to immediately shut that front door when she feels threatened in any way. Mabel's caretakers frequently laugh at her and sometimes point their fingers at her as she struggles to move along. The caretakers allow Mabel only small rations of food and water each day, and they never give her a shower. Where are the abuse investigators? Where is the justice? Or are things not as bad as they appear to be for Mabel?
