Imagine it’s a language, like Chinese. And you don’t speak it. But you go to Chinatown several times a week. And you can kind of understand the Chinese speakers on an emotional level. You can tell when they’re friendly or upset. You can make out their intention sometimes with hand gestures and body language.
You don’t need to speak Chinese for survival. You’ll be fine without it.
But you’d like to be more fluent so you can interact with the folks in Chinatown when you visit. Because when you can speak their language you make your world bigger. More of life becomes clear to you. You have different and deeper insights. Etc.
