Read the eyes, they tell you a lot. Feel the hands, they tell you a lot. Read the lips, they deliver more than a message. From all three you will get their intention.
Just pay attention to their motives.
Words might be coded, and eyes might wink. But words leaping from two lips has serious reactions.
Just pay attention.
There is not a part of the body that doesn't acts out. Word of expression of joy that might you shout.
Eyes, hands, and lips, all are dangerous. Just pay attention.
