mystery

In the office I often deal with the project in Sierra Leone. Every time I get sent something important from there, the papers I tightly rolled. So, I open remove the tape and unroll the papers, roll them again into the other direction, read them, press them and put them nicely into a folder.

The rolling applies to any piece of paper that is even remotely important. Nobody has been able to explain to me why do they do it, so I keep unrolling them and rolling them into the other direction.

Still, I wonder why? What is the secret and magic of rolling?
