Cryptography in Italy

I am currently taking Italian as my language.  We all know that Italians like to speak with their hands.  Although the crazy waving of the hands may seem over the top, many arm motions and hand symbols have special meanings in Italy.  The first, obvious example is the rubbing of the belly: to be hungry.  But there are dozens of other symbols that Italians use to share their ideas.  For example, if you point your index finger on your cheek and twist it around, you are telling somebody that what you just ate was delicious. In addition, if you pinch your index finger and thumb together on both hands you are indicating that something is perfect.  Finally, if you hold out your hand with the palm facing up and move your hand up and down, you are basically saying "How Annoying!" Many people from other cultures do not know the meaning of the Italian hand gestures.  There are many more examples but I just wanted to share a few. I like to think that Italians use their own form of cryptography to communicate in silence.
