Rain.

It began to rain while we sat on the train in our shorts and t-shirts. No one had brought anything more than a light cardigan and most of us did not even have that. The rain in Italy is seldom, grand, and short. Because of its brevity, the Italians are willing to wait it out. Unlike Seattle, when it rains the streets clear out. By the time we reached the hotel the rain had stopped and the streets were again clean.
