I met this person last week and have thought about her a lot. She simply cannot let music become a background thing as she has plenty else going on in her mind, so she chooses not to listen to music.
It struck me that I have a similar reaction to taking in artistic media that might overpower what is already active inside of me. I don't need or want interference with the new routings that are taking place.
What a relief to be able to concentrate at last after so many years of feeling I had to keep up with everything.
