To the Administrator: The people in your employ have all made my father’s life better. The commitment and care they have provided to my Father has been exceptional. I do not know how you have accomplished this atmosphere of excellence but I do think you should not stop what are doing. Do not stop. Remain as you are. You are quality. There is no substitute. Quality comes from caring, for your own as much as for others
