Like that guy who we tried to explain that we'd seen a boat race to. The words boat and victory/victoria led him to believe that we were talking about a large ship called Victoria that happened to be in the harbor at the moment. How we met this guy? Well, we were going to the beach, which meant walk to the bus for 15 minutes, and taking a bus ride for 20 minutes. He happened to be leaving for somewhere in that direction at the same time when we met him outside our hotel so he offered to take us along to the beach. Making him understand what the boat race was took ten minutes, and the constant misunderstandings created a lot of laughter for all of us.
Or that time that we were trying to find our way to the hotel in Gallipoli but didn't know exactly where it was as we didn't have a map, or anyone who knew english. - The tourist bureaus were all closed right then and we couldn't use the internet due to how expensive it would be. - I think we ended up walking for about 8 kilometer to reach the hotel two kilometers away from the bus stop. The reason was that every time we asked a person for directions all other nearby Italians who overheard tried to help us too, so eager to help that they didn't seem to care about if they knew the way or not. We finally ended up at the right place when a man left his friends to walk with us five hundred meters to a cop who happily showed us the last turns.
About the yelling at each other: Well, all parts seemed to enjoy it as they were all smiling again about half a minute after the conversation. The same goes for the honking, whoever we was in a car with waved and honked back. After a while we realised that it's just normal behavior and that none of it was serious.
Well, that's my impression of Italians :)
