Yes, best to assume you’re always misunderstanding, or at least not understanding completely, a conversational comment until you have a holistic understanding of where they’re coming from (ie you become familiar with them and how they think and what they value).
For sure, and with even a teensy bit of reflection I think most people would agree that people are generally quite shit at expressing themselves with words. We say things we don’t mean or imply things we didn’t intend to all the time. A well written book or article takes hundreds of hours of re-writing and getting feedback and re-writing again just to try to communicate the author’s idea effectively. Snap judgments based on social media posts alone are pretty baseless.
