In times even that is no good, they will agree to more flexibility in relationships of close relatives and grown children. Therefore a letter of introductions is indispensable. Regarding that letter of introductions, if the person using it to become a retainer falls into disgrace, the evaluation of the one writing it will fall as well. Therefore they won’t write a letter of introductions for a person they don’t know well enough in the first place.” (Rüdiger)
