My mother is 83 and has dementia. She has good and bad days. Last week she awoke in the morning and was very confused about where she was and was asking where my father was. He has been gone for 26 years now. When I told her that Dad was gone, she cried and screamed for almost an hour until I could calm her down. Should I have told her that Dad was gone? What's the best way to answer questions like this? Is it best to start telling little white lies to keep them calm?
