serbs moving onto attacking with acid

belgrade, serbia, september 19th 2017: since occasionally dealing with and testing silver and gold I can recognize the acrid smell of acid and as I was walking today on vojvode stepe blvd around 19:30 pm I suddenly smelled what appeared to be a pungent acid smell. i noticed many strange behaving serbs too. as I got home I feel strong burning and discomfort around and in my right eye, my forehead and hook of my nose. I believe that someone somewhere somehow sprayed acid on me as I was walking by.
