I recently met a woman, who, after learning about mirror reading, tried to write some words in mirror text.
Interestingly, what she produced was actually upside-down – and perfect. She says she practices during meetings. When she again tried to mirror write, she was able to do it, but said she had to think about it. Upside down was easy for her- she could do it on “auto-pilot” because she was used to it. Fascinated, she wants to continue mirror writing. The best part for me was that she laughed a lot throughout the experiment, a wonderful common response.
