I think dutch and danish sound very similar. Dutch has more sounds coming from the back of the mouth, but it still takes me a while to figure out which language I'm listening to
"Sounds like English from across the room, then I get closer and it still sounds like English spoken across the room" = Dutch
Similarly, when it sounds like English, but I can't understand a single word, I yell at the zoomers to get off my lawn.
(I speak fluent Swedish)
Sounds kind of like Swedish, but I can't understand a single word? = Danish
