volume

I thought it was interesting what you wrote about the volume of Italians talking. I, too, have seen this. As you learn more Italian and become familiar with the culture, you will see/hear people talking at different volumes. Generally speaking you are correct. When they are involved or impassioned, the level goes up. But, I also noted that often the silence of Italians was louder and carried more of an impact than the loudness did. Also, try to figure out the socio-economic level of the Italians that you are observing. There is definitely a difference.
