Abstract
Playing is children 's universe, their trade and their profession, which we leave behind when we grow up and become adults. But it is also true that we adults play on special occasions with our children, such as at family parties. We still have to discover that we can play among adults, in the same way
as we read books. We believe that playing is fundamental in being a person, as it evokes pleasure and happiness. Everyone looks for happiness and wants it in their live. We adults have a lot to leam about the potentiality of the world of play.
