Many Italians live in pretty small spaces so they enjoy the opportunity to get out and enjoy some fresh air. Many gather on large piazzas which turn into living rooms during peak hours (usually 17:00-19:00) - Especially on the weekends. This ritual stroll is popular with all ages, but especially the youngsters who enjoy socializing and flirting with one another. Of course, many of the older Italian men don't grow out of this.
While in Rome I started my passeggiata at Piazza del Popollo (near the Spanish Steps) and walked down Via del Corso. It was full of people doing what the Italians do best - Absolutely nothing.
This doesn't come easily to me - The achiever who thrives on getting things done. While everyone else was strolling I was darting in and out of people. What was the reason for my hurry? Habit! Clearly I have a thing or two to learn from the Italian people.
