Don't even think about going to the post office today. Our local post office is under attack. There is a queue of currently not-so-legal immigrants waiting to hand in, I think, their 'regularisation kits' so they can become legal residents in Italy.
Stop reading, start speaking
Stop translating in your head and start speaking Italian for real with the only audio course that prompt you to speak.
There are so many hopefuls that they have even stationed a number of policemen outside the post office and I suspect the scene is similar throughout Milan, if not Italy, with the possible exception of a few isolated post offices in some out of the way mountain hamlets.
