During my daily visit to Frank he was most anxious to tell me some story of events in the care home. I listened carefully and gave him my full attention. At the end of the story he asked me, as clear as daylight, if I agreed with him, and was it true? I try to let him think I can understand what he says, his speech has deteriorated over the past weeks, but not his desire to speak. Should i know how to react to this?
