speechless

Sometimes I forget how to talk.I asked my teacher or my close friends a lot the question a lot a few years ago."What do you talk about when you are dealing with people you barely know?"Perhaps I have become more able to manipulate on this kind of skill so now I don't usually worry much about that.Somehow other kind of questions come up to me. Don't really feel like talking. Even with close friends I can be really impatient. Not all the time, but often enough for me to notice that. For people I barely know. I do not what to say and that is not because I don't know about what to say but rather I am just not in a mood of making new friends. Of course we don't always categorize different friends and make a label on them, but it seems we all tend to hang out with those we are more favorable with. It's normal and totally understandable, but is that a problem?I am lost...maybe not only does bad answer exist, but also does bad question.
