Socially, encoxada depends on the crowd’s muteness. On buses in tight-quarters cities, proximity is a social contract: we accept nearness to strangers because we accept vulnerability for the price of transit. The violation is that it converts that shared vulnerability into a weapon. The offender relies on the bus’s transitory anonymity—the knowledge that people will look away, that passengers will prioritize ease over confrontation. Some avert their eyes, some glance and return to their phones, some shrink into their shells as if the act were contagious and recognition would make things worse. The one who is touched is often handed a new kind of labor: to decide whether to escalate, to speak, to document with a phone, to stand and move into the aisle, or to carry the weight of silence home.
