Yes, I vaguely remember that my Dad at that time was serving as the director of the MK school, because the property was on AG grounds so only an AG missionary could do that job, when the Sanchez family demanded the destruction of certain odd books that were kept locked in a closet. I only had occasion once or twice to glimpse the contents of the closet, when Dawn was allowed in there and showed me a few things about that. There were certain books in probably Swedish that we could not read, only peruse the peculiar drawings, indicating their "sociological" purpose, probably. Also there were some books that had been eaten by bookworms during a previous setting, probably Brazil, so that there were holes bored directly through the middle of the books, making it sometimes difficult to read the pages with holes in the middle of the text. There was a book burning and some of those books were burned for various reasons. The Sanchez family and their people demanded the book burning, so my parents had to do it. Personally I would not put too much stock in the Sanchez opinions of anything, but sometimes when they are in certain positions they make it hard for us to forget about their existence, and the fact that in their own homes they harbor strange books about Russian spies and who knows what else, so who are they to lecture white people about books?
