My 88 year old mother has developed into a terror. A very mean demeanor.....arguing, cussing and everything is negative with her. It's amazing what us caregivers have to put up with. These old people lose part of their mind in the aging process and the ones taking care of them are on the receiving end of their wrath. It's absolutely mind-boggling with all the problems these elders develop......not just physical problems, but the resistance they dish out to those that are trying to care for them. Instead of making it easy for their caregivers.....these elders make it hell. I deal with it every day. It's terrible what the aging process does to the human body!
