I almost forgot to mention!!! On the train home we were sitting in our own little sealed off section when 2 Italian police officers came in and started talking. Andrea reached for his bag but I had no clue what was going on. I looked at Andrea asking if we had to go somewhere and he said no, they are just looking for identification. We all pulled out our ID's and handed them over. They studied my passport for a while and Andrea noticed that the officer mentioned that it was a passport from the United States. They took down the information from all our ID's, held Andrea's the longest, and kept moving.
It was the first time that this has happened to Andrea and he rides the train quite frequently. I am just glad that he was there as I had gotten quite nervous not knowing what they were saying!!
