I found this little gem on Facebook (or is it Meta now) and saved it. If anyone ever asks you why you play with Little Men then cite Peter Cushing's take on the hobby.
I find myself worrying about what people will think when they learn that I war game. Oftentimes they are fascinated by my hobby and ask me lots and lots of questions about it. I guess that the take away is this:
Enjoy your hobby and don't worry about what anyone else thinks about it.
