The development of science and technology seems to be increasing distance
between people. So how can we show our desire to get closer to people? The
answer is by smiling. Smiling dissolves apathy and distributes warmth. Smiling
is an international language. Even if you go abroad and don't speak the
language, a smile will carry you a long way. Try and wear a smile on your face
frequently, and you will get an unexpected response in return.
