TFW you are on a commuter train between Varese (Italy) and Como (Italy) and an announcement warns you that you are now leaving the European Union!!1ONE!!! (and if you are carrying about a truckload of money or valuables you should leave the train at the next station to declare them)

(I knew I was going to leave Italy for part of the trip, I just didn't expect the EU bit)
