Pru is extremely busy writing letters, and it's a very complicated business. First she writes the letter, then she encloses a photograph of herself, then makes a lipstick kiss print and then she sprays it with perfume - no wonder she hasn't got time to play. Finally the letters are ready to post, and all the friends receive one. All except Pru. Will the friends come up with a plan to make sure that Pru gets something special through the letter box?
