I wonder if he does it to see if I'm truly awake and listening at that time of the morning!!
(The real story is of St Frances of Rome who was reciting the Office of the Blessed Virgin, she was interrupted four times by the voice of her husband calling her. Each time she answered promptly, and when she returned the fourth time, she found the antiphon written in letters of gold. So that's why all that gold writing keeps appearing in my prayer books eh?).
