What is the difference between these two gestures:
tips of fingers and tip of thumb together on one hand, pointing upwards, often with an up-and-down movement (i.e. the classic "Che vuoi?" gesture)
tips of fingers of left hand lightly touching those of right hand, with the tips of the thumb of each hand also touching (separately), with an up-and-down movement
It seems to me that the two gestures are very similar, and all I can observe is that the first gesture is more aggressive. How should they be used?
