I used to do that too. forgot to read the notes. hahaaa I am going to try and tell you what else my father said. he shook very badly. sometimes the trembles were worse then others. He said he went to the bathroom and umm 3 times before he could make his hand let go.
My Mother had dementia,she would take a shower,in about an hour she would do it again,because she wouldn't remember doing it the first time.
If I don't do thinks in the correct order in the shower I forget if I have washed my hair or just gotten it wet! Then I have to wash it again to be sure!
