Imagine you enjoying lunch in the food court when, suddenly, an unknown girl gets up and starts shooting everywhere... (⊙_◎) (⑉⊙ȏ⊙)
Fortunately, what I quoted was just an example - we don't live in a fiction, thank God (!).
I'm sorry to be the bringer of bad news, but ... the USA is a real place.
USA ain’t an fantasy place were this thing happens out of no were, i know let’s bas USA and all of that weird crap but really??
Uhhhh . . . it actually is, though. That's exactly what happens, people in some public place are minding their own business and some shooter opens up and kills a bunch of them. It's in the headlines all the time. Schools, night clubs, movie theatres, convenience stores, a massage parlor . . . I believe the US has passed the one per day mark.
Now the US is a big place--that still means you're probably going to live your whole life without ever having it happen right near you. But still--yes, the US is, as you put it, a fantasy place where this thing happens out of nowhere. No other country has anything like it.
