First, an individual has to be a good listener- while words do matter, most of the time, we communicate through nonverbal cues. Even if someone avoids talking to a certain person, this is also a kind of communication. Listening to a person can be a both way communication. If I speak something intending to inform someone about something and the person hears me, understands me and affirms me that he understood; then my communication is effective. In case if the person would not have heard me or would not have understood me, then it could have been called ‘ineffective communication’.
