Q The spouses of two of my friends have Alzheimer’s disease. Unfortunately, they continue to drive despite dents in their cars and periodically getting lost. My friends are doing nothing and are waiting for their doctors to take on the problem. None have done so. To me, it is a moral responsibility to keep our loved ones safe, out of accidents and situations that can cause harm to others. Is this something I can talk with my friends about or do I need to keep biting my tongue?
