A stranger is running at you in an agitated state -- you can't quite tell if the expression is frightened, threatening, angry -- holding something that kind of looks like a handgun.
jūsu virzienā skrien satraukts svešinieks, – jūs īsti nevarat pateikt, vai sejā ir bailes, draudi, dusmas, – turot rokā kaut ko, kas izskatās pēc pistoles.
