She is 83, has mild dementia and nerve damage in her legs, along with osteoarthritis in her knees. She uses a walker to get around. She gets up around 10:30 a.m., piddles around the house, does the crossword puzzle until she loses interest, then naps during the day while watching TV. She goes to bed around 10:00 p.m., but for the last month she calls me anywhere between 2:00 and 4:00 a.m. I am exhausted because I cant get back to sleep and have to work.
