I had a different childhood than most kids. Both my parents served in the US Navy, and I spent almost my entire early and formative years overseas. Whether through AFRTS (armed forces radio television) indoctrination or just plain old childhood observation, I learned that it was important that I never present a myself as a tourist.
Tourists are targets.
At least that is what I remember thinking as a child.
Also, American tourists, in my experience were horrible people. I would see them in airports and hotels and quite vividly remember being appalled at their behaviour. They were always so very loud and obnoxious. I witnessed their pushy and entitled demeanor and was embarrassed. Whenever I travelled, I would even deliberately hide my accent in an attempt to hide my Americanism from anyone I might encounter just to remove what appeared to me, to be a very embarrassing association. Don't be a tourist, but if you're going to be one especially don't be an American one.
