A seemingly dying tradition in Italy involves tossing old personal items directly out of the window. Be careful... even though it's not done all that often, you might still come across unexplained personal trash laying on the streets below apartment blocks. Keep an eye out while strolling around on New Year's Eve, just in case!
Another old ritual involves smashing plates, glasses, vases and other pottery against the ground to drive away any bad omens that might infect the New Year, beginning everything anew. Some might do this in their house, but you will often see broken china laying at the curbside... something else to watch out for!
