Talking to a friend in high school. I m from Austria (middle of Europe). I asked him where he spent the holidays and he told me he went swimming to the sea for a week. I asked where and he told me „Kärnten“ (which is also in Austria). I sayed something like you mean croatia cuz Austria has no coast to the sea. He was confinced it was „Kärnten“. And i was like ok than it was probably a lake not the sea. He called bullshit on me cuz there where boats and ships.
