Remember when my daughter asked to read a proof of my book? Well, here’s what happened: she finished it over a few days and on the last day, she fell asleep with it, woke up in the morning and continued reading until she was done. I was away at the time and we talked briefly about it over Skype (partial conversation in image below).
She had three great suggestions, none of which I would have thought of by myself, and she gave me a grade of 9. Actually, that grade was 8.5 to start with, and when I got home she upgraded it to a 9.
