The Navy is trying to recruite me

I received a packet in the mail from the Navy. They are trying to recruite me to become a Naval Officer. I don't know what I would do in the Navy. I don't think it's my cup of tea. I don't know how they got ahold of me, except that maybe I filled something out online when I was looking at information about the Air Force Reserve. I am not pursuing the Reserve thing as of yet, as I have many other things on my mind, and no hurry.
