The eyes and facial expression of a listener are important to a speaker. If a listener is rolling her eyes, has a bored expression or seems glazed over, these are blatant cues that the listener is not actually listening or does not care about the speaker has to say. Make eye contact during conversations and take care that your facial expression is one of alertness and caring. Although not an actual "facial" expression, head movements such as nodding are also important visual cues that let people know you are listening, processing the information and care about what is being said.
