Growing up in a military family allowed me to see a fair bit of the world -- and required me to learn to adapt to different cultures and customs every time we moved. Then I read (or heard?) the phrase "...the things are also people" in a SF story.
Even though I travel a lot less with my own family, the wanderlust has never completely gone away -- or the curiousity about cultures and customs strange and wonderful, and I've written about people (or things that are also people) dealing with unusual cultural situations ever since.
So shoulder your backpack, tuck your blaster into your belt or your dagger in your boot, and join me in the journey!
