Meeting someone's glance with your eyes is usually a sign of involvement, whereas looking away often signals a desire to avoid contact. This is whysolicitors on the street – panhandlers (beggars), salespeople, petitioners -- try to catch our eye. Once they've managed to establish contact with a glance, it becomes harder for the approached person to draw away. Most of us remember trying to avoid a question we didn't understand by glancing away from the teacher. At times like these we usually became very interested in our textbooks, fingernails, the clock -- anything but the teacher's stare.
