The correct answer to this open question is the following.
An implicit form of communication, when someone winks when it says the statement “I'm joking,” is that the wink represents a nonverbal communication that transmits the idea of "we're good, right?" or "everything is OK, right?"
Nonverbal communication helps people to reinforce their ideas or transmission to strengthen their message and make the receptor to clearly understand what the transmitter wants to convey.
