She lives alone in a first floor garden apt in NYC. She told me someone flashed a light into her bedroom window at exactly 9:00 p.m., 12:00 a.m., 3:00 a.m. and 6:00 a.m. so she called the police in the morning. They came and looked around, and told her she should call as it is happening instead of waiting for the morning. A few months ago, she said a man was looking in her front window as she was sitting in her chair, and she opened the door to confront him. That time she did not call them. I am really worried that she is starting to lose it, even though she had a brain workup at a neurologist who said her brain is in great shape. She has pretty severe short term memory loss, so I do not believe much that she tells me. She can be pretty rude when I try to reason with her if something does not make sense. At what point does one bring in a caregiver? She is very independent as far as getting herself to the senior center on the public bus for exercise three days a week, and walks to the grocery. I do keep tabs on her bank accounts and bills...Thanks all!
