When I was spending my summer holidays in Italy, I was surprised by the way Italians spend their spare time together ,and have lots of fun dancing and singing. There, it was really noisy. The atmosphere was unique. But ,at bottom, that could mean everything. That was the first thought after a kind of doubt in the simplicity of this phenomenon and the reliability of the first impression. For example, this way they can hide the dark part of their lives full of dramatic experiences about which we have no idea as tourists. When it comes to our awareness, all these loud sounds are becoming our point of curiosity. We have finally a chance to analyze e every single voice we are able to hear.
