Answer:
Regulating interaction.
Explanation:
We can regulate our interaction with others through several manners. Since it is a nonverbal code, regulating interaction can take place through gestures, body language, stares or lack of eye contact, etc. For example, it is common for men to avoid eye contact with others when they do not wish to be interrupted, when they wish to "hold onto the talk stage". It is also usual for woman to invite someone in a group to speak by simply looking and smiling at them. Those are just a couple of examples, but there are several other possibilities. They help keep the flow of the conversation going, or avoid interruptions, and can happen anywhere - among family and friends, at work, at school, etc.
