Did you always like being up late or had to because of your job?
I was ALWAYS a night owl! Then I got used to it even more when I waitressed and bartended my way through college. I hated being up in the early morning hours and leaving in the afternoon with all that traffic. I even changed my daytime shift to 10am until 7pm so I didnt have to deal with it. I also liked the idea of the night shift with having kids.
