The twin in cryptology

[Aga Tentakulus]

I'm pretty sure today that one problem is that you can't see properly.
If you look at the scripture too long, everything becomes blurred and everything looks the same.
I think LisaFaginDavis has had the same experience. After 20 minutes it's already finished. You can't see the details any more.
Also in this example, small change, big effect.
When does a combination become an ending?

   

@LisaFaginDavis, is a good idea to include the line number. I spent most of my time trying to find the details again. That's why I do it that way now.


And then you have to be aware of the details.
If you don't know the small differences in today's writing, you simply can't read.
