Then there are some of us who refuse to dump their parents in a rest home for fear of their abuse or lonliness or both.
There's no such thing as a "rest home" and you might've been in some to know that for yourself. They're like cattle pens with the odor of urine stinging at your eyes when you just open the door. There's no dignity. Patients are left to rot away, marooned on wheel chairs, stewing in their own waste. It's a horrible sight, some of these facilities.
There are some with youngins of there own to care for. What you really wish you could do, you can't always do.
