Do not look at your interlocutor too closely
It happens that too close and open eyes can make your interlocutor be embarrassed and feel inconvenient, uncomfortable in your company. To avoid this, you should not too carefully consider your interlocutor, or constantly “stare” at one selected point on his face (for example, between eyes, on the nose). Expand your visual contact area. Let your eyes will not always be straight. For example, listening to your interlocutor, quickly “walk” with a look at his face to express your interest.
