Well, I have two best friends besides my wife, a guy and a girl. My girl friend does not like to talk about things she considers "negative" aka anything serious while high. Which is cool because she uses it to lift her mood, and relax. We have had a lot of fun being silly together, and making each other laugh. My guy friend is a very serious passionate person. We end up talking a lot about music, politics, science, and philosophy. I can't really name a specific conversation, but I usually have good conversations with fellow stoners.

I think it opens up your mind, and you think about things that you would never think about. It has a very positive vibe to it. Of course, if you want to you can always choose to be rude or ignorant while high. I choose to be mellow and reflective.
