Talking With Friends

I just read about an interesting study that concluded that people who share deep conversation are happier than those who limit their talking to small talk. There were a lot of comments about the post, and the majority of commenters preferred deep conversations. It made me think about me and about my friends and about what we talk about. I get tired of small talk very quickly; after all, I can talk about the weather with anyone. I can't talk about the details of my life or my feelings with just anyone, so when I spend time with a trusted friend, I want to make the most out of the opportunity. This doesn't mean I want to sit around in a drum circle and analyze my feelings, but I do prefer talking about why we do what we do or think the way we think, etc. What about you? What kind of talking do you prefer?
