Another reason for doing this is that I always wanted to teach, and this is a way that I can share what knowledge I have with members of the public. I enjoy talking to the public and interacting with people, this gives me the chance to do this.
Last of all, I consider reenactors all extended members of my family. As a matter of fact, I am closer to my fellow reenactors than I am to some of my blood kinfolk (but if you knew some of my relatives, well, that statement wouldn't sound QUITE so strong)
I remember once being lectured by a fellow when I called what I did a hobby. He told me that it involved a heck of a lot more than a hobby, it was more like a life style or way of living. At that point, I had to agree with him, so I started calling it with my tongue firmly planted in my cheek,"This thing of ours" Well, some of you might know that is the English translation of the term, La Cosa Nostra. Once in, never out.
