Use your eyes, ears and heart
Communication boils down to listening with three organs - the eyes, the ears and the heart, according to Mike Harsh, associate professor of speech, theater and English at Hagerstown Junior College.
Harsh says flirting can be fun to watch.
"You can tell who's hot for whom in a college class," he says.
But the skills involved in flirting have broader applications. Body language is vitally important during an job interview, Harsh says.
And with consciousness raised about sexual harassment in the workplace, it's important to know how to avoid appearing too forward, Harsh says.
The latest in the study of nonverbal communication deals with reading body language clusters, according to Harsh.
The face, eyes, shoulders, body orientation, proximity and posture all are part of a signal. Harsh compares it to looking at a traffic light with go, slow down and stop signals.
