Any one else?

I seem to lack the thing that enables most people, when they first begin to interact, to do so smoothly. I seem to be some how stalled. With out the opportunity to have a full conversation with someone I lack the report that I require in order to banter with them. I feel like I am constantly missing the joke as all those around me laugh together and interact so comfortably. I have no way to penetrate that invisible barrier. With out the chance to explain my self I am constantly aware that what I may say could be taken the wrong way. With people I have no further need to interact with I am ok (I don’t really care what they think anyway; people whom I can interact with one on one are usually fantastic - i’ve even made a few good friends this way. It is when people form groups and I have no way to interact with one and not the others that I struggle; I feel unnecessary - I know that their interaction doesn't need my input and will continue regardless. So I am left with the impression that I’ve witnessed a moment between two or three of them yet am unable to leave graciously or join. Regardless of my reactions I feel silly and conspicuous. No wonder I prefer to be alone.
