You speak a minority language and will never persuade the majority to learn yours. On the other hand, it takes two to tango, and if they can't extricate themselves from an unwanted conversation with you, then either they aren't trying very hard (because they're passive-aggressive) or their social skills have limits just like yours. Either way, it's a combination of their weakness with yours that leads to awkwardness. By all means keep working on your skills, but try to see "normal" people as falling into a spectrum of social ability that you also fall into (deep in one end, apparently, but you'll be surprised how close some "normal" people come.)
