There is one thing, Italians hate even more than leaving the house without the cellphone: leaving the house walking. Italians just don´t walk! Feet exist to play soccer or, in case they are feminine to be admired, but never for bridging distances. No distance.
If you see Italians without a noisy car or vespa, they don´t walk – they stroll. Strolling can happen at the waterfront or in the most elegant shopping street in town. It´s about to look as good as possible while you´re strolling very slowly along, chatting (you never stroll alone) and eating gelato. You definitely avoid the impression you might want to go somewhere, it´s for sure not to get from A to B! Because that would be translated into Italian either you can´t afford a car or you had to pass your driving license to the local police station, both is unacceptably!
