Some years ago, in the initial interview with a young adult Norwegian non-reader, I got the following amazing and thought provoking information: "You know, I tried to get away from the problem by going to sea. Boy, did I feel lonesome out there. I was not able to read the few letters my parents wrote me, and asking one of the other guys to read them to me would make him know about my problem. I tried to write my mother a letter one day, but I gave it up and threw it in the ocean. And there were lots of things that I would have to read in order to do my job properly and take part in the activities on board: posters, signs and notices. I could not read them, and I tried hard to keep the others from knowing that I was not able to."
