I'm so tired of hearing that word online.
True: Nobody is entitled to be treated nicely. Nobody is entitled to an open, friendly relationship. Nobody is entitled to get to know you. If we only did what we were entitled to do, and received what we were entitled to receive, the world would be an even shittier place than it already is. We have enough people walking around with the "You're not entitled to me being nice, so I'm not gonna be! nyaaaaa!" attitudes.
and acťually i believe the opposite is true: we are entitled to be treated nicely. we are entitled to an open and friendly relationship. and while i agree that we are not entitled to get to know you, i'd prefer to deal with an authentic person, because hiding behind a generic facade makes it easier for someone to impersonate you, putting you at risk of becoming a victim of identity theft.
