Do people on your job only seem to want to engage in a silly conversation?

For saying stuff just for the sake of saying it and not for any real meaning or connection. People don't seem to like thoughtful conversations just a bunch of silly stuff.

I am very observant. My co-workers, whom i share an open office with, talk outloud to themselves, and/ or about what they're doing so that other co-workers can chime in and make a conversation out of it. I find it weird.

I cant even explain how weird it is. As soon as it is quiet for like 2 minutes, people say " uh its so quiet" as if quietness hurts their ears.
