Grace very much wanted to attend the Unity Feast at West Englewood, the Feast given by ‘Abdu’l-Bahá and now commemorated every year. But Dr Krug said Saturday was his only free day, and he wanted her to play golf with him. She asked the Master what to do. ‘Abdu’l-Bahá said: ‘You must always consider the Doctor. You and Miss Krug must play golf with him.’ So she and her young daughter had to go to the country club, not more than a mile from the Unity Feast—and play golf. The Doctor became a Bahá’í, and both he and Grace were present in Haifa (1921), when the Master left this life.
