Do's and Don'ts of Italy

There are many cultural do's and don'ts I've observed in Italy.

DO
get dressed up, all the time
drink espresso instead of eating breakfast
look angry all the time when walking down the street
stand really close to everyone, everywhere
ride a vespa in stiletto's
(girls) hold hands with your friends. I don't get it.
pay for whatever food you want before you go to the counter to get it
use 5 people to do a 1 person job
show a lot of PDA
attend protests

DO NOT
eat or drink while walking
acknowledge anything a man says to you on the street. Even if he is right next to you, yelling in your ear, just act like he doesn't exist and he'll go away soon
drink cappucino except in the morning. Huge faux pas
run. ever. even if that car looks like it's going to hit you, just walk
get drunk
slowly sip an espresso. Drink it in a few quick sips
sweat
show cleavage. No one has boobs
use a washing machine/dryer

That's all for now, I have to go do homework : ( I'll add more if I think about them.
