(A) Mastering nonverbal signals will allow you to "read someone like a book."
Step-by-step explanation:
Nonverbal communication refers to all the ways peop`le can communicate without using language like:
- tone of voice
- gestures
- posture
- eye contact
- body language
It is more probably that people inccur into nonverbal language without know they do so. In most of the time is unconsciosly
