A package was delivered  to her, with a card that read: Dear Joyce, I forget to send you the package  that you should have received on May 20, 1956, your fifth birthday. The gift inside has aged, but I felt that you might still wish to have it. Angel of Joy Joyce opened the package and saw a lovely grandma doll.
