Interpersonal communication is probably the most widely utilized, accepted, and studied communication in the world. It occurs between two people. Both people have to relate to each other pertaining to a certain subject, topic, or commonality they share.
There is also something called small group communication, which falls under the umbrella of interpersonal communication. In this type of communication, each person will play the sender and receiver's role while switching back and forth between each other in conversation.
Small group communication typically involves more than two people. Everyone within the group is expected to listen and understand and inject their own opinions or perspectives into the mix.
Verbal communication includes face to face conversations between two people. When it comes to communication, nonverbal is just as important as the words that come out of our mouths. Nonverbal communication can convey a deeper level of emotions than our words say.
Facial expressions can be things like an eye roll, which shows annoyance or a smile, which shows happiness. Body Movement can be a shrug or a head shake, saying no or yes. Space between two people can show that they do not want to be close. Lastly, an aggressive voice could mean one is angry.
