Zone One, Second Post

After reading to page 149 I have grown to like the book a lot, I want to see what is going to happen and what they are going to do next. However, I still don't like how the book is written I have a vary hard time following it at times. The author can be talking about the present time at one point then flash back in time without a good transition leaving me confused on rather or not we are in the present or future.With that I noticed reading more into the book that Mark Spitz in more into talking about the future later in the book then he was in the beginning.  Another thing that has been bothering me while I was reading was that he talks about Last Night a lot, what does he mean by this? Is it a representation of his last night of the world being normal before the sickness broke out? Another thing that came to my attention was that Mark starts to see the zombies as humans, noticing that they call the stragglers male or female but they refer to the skels as its.  What is the difference between he two names and why do they call the stragglers male or female and the skels its?
