So, what do your people talk about? That’s the general topic. Within a group of people, there’s always one (or many) recurring conversation topics determined by the group’s identity. For example, when mechanics get together, they don’t talk about philosophy. That doesn’t mean mechanics aren’t interested in philosophy; it just means that’s not what they generally talk about together. What makes the world beautiful is that we live our lives in different communities. If we only hang out with one group of people, we’d miss out on the richness of life and valuable opportunities.
