Good part: My fantastically gifted daughter-in-law took time out from her thousand-hour-a-week work schedule to critique three chapters of my manuscript. She said many very nice things and also pointed out some potentially fatal (yet fixable) shortcomings.
Bad part: My brain turned on and wouldn’t turn off. I wrote until 3:30 and got up at 7:30. Almost afraid to review my changes, which, though they seemed brilliant at the time, may read more like, “See Spot run. Run, Spot. Run!”
