Well there's this mysterious phenomenon called a 'context' which can determine ultimately whether somethings used in positive sense, negative sense or apathetically. As a case in point - 'that was shit' - negative, 'that shit was unreal' - positive, 'what is all this shit' - neutral. OK? Is that clear now?
Keep your social incompetence to yourself. Thank you.
And don't worry - if all it takes for your to get worked up is a misunderstanding a flippant comment due to a lack of basic comprehension, you're probably a nightmare to deal with professionally too. I will make sure I avoid your 'traffic arbitrage' service at all costs
