What a delightful anecdote, Kim Martin!
Thanks for sharing it with us here. As for your grandfather teaching you the word “cogitate”, this too is wonderful.
I was raised by books because my mother discovered they had the power to keep me quiet for hours. Whenever my parents decided I deserved a treat, they’d always ask if I wanted candy or books. I never picked candy, and what they spent on books they saved on dentist visits! :-)
