For example, you are trying to explain to the barista what kind of coffee you want. In your head there is a clear order: "Latte with oat milk, without syrup, but with a light foam." And from your mouth comes out something like: "Eh... well, just a latte... but not quite... you can, but without... oh, okay, as usual!" - and now you are already drinking something completely unexpected.
Or even cooler - correspondence. You wrote "Hi" to someone, and in response - just a smiley. What was that?! Joy? Disdain? Or did he accidentally drop his phone? How can you not go crazy here?
But the highest level of difficulty is to decipher other people's hints. Because "I'm not angry" means "I am." "Do as you wish" means "Do as I want, otherwise it's the end." "I don't care" - it really does, just figure it out yourself! In general, yes, communication is an art. And if you manage to say what you want and be understood without explanatory pictures and dances, congratulations! You are either a genius or a telepath. And everyone else can only hope for the power of emoji and patience. 😅
