The elderly man hurried to his doctor appointment. He wanted to rush because he had to be somewhere by 9a.m. The doctor asked where he was going. He said that every morning he is at the nursing home to eat breakfast with his wife. He then said that his wife had Alzheimers disease and for the past 5 years she hasn't known who he is. The doctor was surprised and asked the man why he continues to go faithfully if she has no idea who he is....the old man replied, "because I still know who she is."
