1. Great manners which can fool you: right girls, of course depending on where you come from this is either exagerated or absolutely true. Say you are from the Netherlands you might think they have great manners, if you are Spanish this quality doesn't impress you much. However it is true that if you have been attention-less for some time, or live in the US for a couple of years, someone actually paying the bill or holding the door might do the job. Acthung! These are only pre-studied behaviors to get you to bed without a pre-notice.
2. Folded underwear: or “Mammone”. If upon arriving at an Italian man's house you notice his laundry smells better than yours, watch out for “Mamma”. The Gentleman might not drive you home after he has achieved his goal, but he will certainly take time of his busy week to bring his laundry to Mamma.
3. VAIN: that is my absolute favorite one. It is true. From the Jersey Shore immigrants who sport this attitude bowing to their Italian ancestors, (they are called “Guidos” for a reason) all the way to the eyebrow shavers here in Italy, there is a whole new range of vanity. Italian men are conceited? Yes, my friends. If you can live with that kind of ego and mirror-obsession go ahead. I'll skip. One time an Italian actor (unfortunately I can't reveal his name and put him to shame) recited an entire theatre act in front of me just to hear himself talk. Needless to say, I (the girl) wasn't too happy with this.
4. One of my girlfriends pointed out infidelity: I think it's a bit out of date... I think Italian girls like the drama and Italian men give it to them. Long lunch hours are not in schedule anymore.
