I don't think I personally am... And although I have never been called an awkward person I sometimes do cause awkward situations? unintentionally of course!
Yes... I have social anxiety though so it's kind of a given for me.
It depends on the situation though. If I'm thrown into a situation where I HAVE to talk to people, I'm fine and make new friends (i.e move from home into University). But I hate those situations when someone talks to you and you genuinely haven't got a clue what to say.
