This is a great description of a person who has Alzheimer’s or some other form of dementia. They see the world through a different window–a window that is flawed, fogged, cracked, or otherwise less than clear, but it is their reality nonetheless. As caregivers, we must try to understand their view rather than attempting the impossible task of making them understand ours. I am reminded of a favorite saying of a former employer: Don’t try to teach a pig to sing. You won’t succeed, and you will only irritate the pig.
