@cryptoitaly and @adsactly, Really deeply explained and subjected about the Expressions, and in my opinion expressions speaks more loudly than the words and voice for sure.
And if we want to identify the next person's feelings then most of the time Facial Expressions becomes the tool and indicator for sure, and we have to just observe it.
And our Body Language tells about the position of our mindset and our Thought Process, that's why when anyone lie then for sure we can easily identify it for sure.
But in my opinion there are many who controlled their expressions and they consciously control their expressions as per the situations and they can Act effectively.
Keep up this informative and deeply subjected work.
Wishing you an great day and stay blessed. 🙂
