Well, despite the fact that it's a prison, it's really not too much of a frightening place. Most people who are here, at least it seems like it, don't really deserve prison. Some crimes have been as ridiculous as 'being selfish'.
For the most part, you should be safe. But there are some individuals...who you should probably be careful of. You'll find too that not everyone here is similar to each other. Not everyone is really human.
