I didn't make it up. I'm not the only person in the world to go through that. When they are offered something to read, they may not read it at all, because they know it is too hard, or they may try to read it, but have so much difficulty that they miss the significance of it. Women who have been told that they were stupid, that they would be unable to look after themselves, that they would never be able to go back to school, find that they can in fact read these easy books. Just tell them what they need to know.
Regular readers find two advantages of print over speech.
First, we can read it again and again. If it is factual stuff that we are trying to remember, we can go back to it as many times as necessary. If it is inspirational, or comforting, we can let it work its magic as often as we need it. Secondly, sometimes we hear something new at a time when we are not able to take it in, because we are tired or under stress. If the new information is also in print, we can save it for later, for a time when we are ready to give it our attention.
