I know it's been a very long time since you have heard from me, but the reasons for not keeping contact are that:
After the 9/11 incident, I was put on Mail Watch (meaning they were reading my letters). So I had to stop receiving your papers because they start to give me problems about "those kind of papers". Which will open people's eyes to what's happening in the world today!
The second reason was because I was working on my cases, trying to free myself from this hell hole!
So I would like to receive your papers again, and I have someone who wants to write to you too. Please start sending him your papers so we can build on what's happening in today's world.
