When will I learn that arguing with a demented person is futile?

You are so right Maggie!

i stood on the front porch and watched my mom stand in the grass and hurl tools into the driveway as far as she could throw them . she was going to die soon and lose her beautiful home . i could see she was hurting . i never spoke a word until she was done then led her back into the house . near the end of life all you can do is follow them closely to catch em if they fall and let em act out . the 4 yr old mentality will regress to 2 or 1 .. it gets harder is all im sayin .

You've learned it. You know it. You just don't always REMEMBER it. ;)

She's probably thinking the same thing.....
