Welcome to the North

Now in the Far North (i.e. Milan!), Alberto has accepted to manage a program for efficiency improvement in the Italian Post. He devotes all his time and all his energy to this noble task and neglects his wife Silvia, which of course annoys her beyond limits. Things do not fare much better in Castellabate where it is rather Maria, Matta's wife, who gets on his nerves by always blaming him for his lack of ambition. One day, due to a misunderstanding, Mattia is transferred to... Milan! And on whose doorstep does he land? Alberto's of course!
