Silence is Golden?

When I'm with a large group of people I'm always compelled to be involved in conversation. I don't know why, but there seems to be something unnatural when a lot of people are together and there's no sound. Unless I'm in a library I think silence is very awkward. This is probably because in our society it seems we're always around noise. I think everyone would be way more relaxed if we didnt feel like we always needed something to say.
