The point of identifying or creating context is to increase the likelihood of someone understanding where you’re coming from. When two people share a common context, they’re more likely to understand each other’s point of view.

For example, if my context is baseball and your context is bowling, we can both talk about getting a strike, but the meaning is very different. If we don’t know that we’re holding different contexts, we’re likely to have difficulty communicating.

If I realize that we have different contexts, I can change mine (share yours), so that we’re more likely to understand each other.
