An experiment with a smile
An experiment with a smile Have you ever thought about how great a smile has in our life? I will not open America, saying that it is huge, because we smile at least ten times a day, or even more often; With a smile we begin acquaintance, we say "I love you"; We smile when we read, when we watch films, wake up or fall asleep ... The smile paints almost every person, makes him “glow”, and disposes to himself.
