Italian people are famous for the expressive way of communicating.
Now, they will often combine the Italian gestures in this video with fast-paced, angry soliloquys, hysterical outbursts, sweet, ironic smiles or even as part of general conversation when relating anecdotes, in which the gestures are not necessarily aimed at the interlocutor.
We recommend employing these at your own risk.
In fact, we recommend first a keen observance of Italian behaviour and social etiquette, after which you may choose to be as conservative or risky as you please.
Enjoy.
