At around age 6 while living in Korea, I somehow came to have a spiffy catalog from America that listed all Fisher-Price toys that were available for mail-order. The catalog had all these incredible toys that neither I nor any of my friends have ever seen. I read that catalog so many times, imagining playing with those toys, until the catalog eventually disintegrated in my hands one day.
The catalog was the book that confirmed to me — who was six, mind you — that America must be the best and the greatest country in the world. Later when I came to America, my faith was validated.
