meaningless chatter

I hear so many people talking who never SAY anything...I am so uninterested in what too many people have to say. I like deep, meaningful conversations... I wonder if I'm a snob? I don't think I am, but I really don't care to interact with people unless they have some kind of purpose in my life...hmmm I think tha t people probably misperceive me... It's kind of a paradox, though, because, at times, I just say whatever is on my mind, however meaningless it is. I guess in certain situations, I hate the quiet, so I talk. I'm slowly starting to see that I get on my own nerves when I do this.
