There is no doubt that it can be difficult to be with someone you know who has forgotten who you are and, indeed, who they are. At times it takes a leap of faith to remember them as the person that you know. But no matter what, your friends remain your friends, don’t they? The ease with which people with dementia can be unfriended raises a dark question: What is it that we actually love in those we claim to love?
