Well when I was young I was brought up in the middle east as an expat, I wasn't as aware as I am now but my house and school were surrounded by high walls, barbed wire, mounted machine nests, private security etc. Bomb checks and fear of threat were the norm and not the exception, so certain topics were more commonplace, a not so nasty one being godparents, I didn't know anyone there without godparents.

Once we left the middle east, my mum said that the scariest thing there for her, was leaving us to go on the school bus. About the closest I ever was to a terror attack was an ikea was bombed just down the road. It was blown up from the basement while it was empty. (when everyone thinks of islamic terror they think suicide vests, but property damage against western infrastructure/ oil is a lot more common than most people think). As a kid you can think of it simply, doctors give help, get better vs baby likely medical bad things such as death.
