Not that many people travel to another country. At least not very often, and having your safety in mind is an extremely important thing. You don't need to worry about the world turning upside down, but it does help to know some travel safety tips to help you have the most fun on your travels.
Recognize authorities
It's a great idea to recognize what the authorities in an area look like, and what they don't look like. It's pretty easy to find a couple of police and notice their uniforms. If someone starts demanding an ID from you and they aren't in uniform, then you should be suspicious and go find a real authority figure. You'll also notice how many of them are in an area. I always feel safer when I know they are around because they are there to help me.
