A Swedish "no"

Sweden is arguably one of the nicest countries to live in in the world by most metrices. That however, does not mean we can't improve. The other day I proposed something for a colleague. The response I got was "let's discuss it". This is Swedish for "I don't think that is a good idea". It should be added that my colleague is my boss.
We really have some communication flaws here. Us Swedes should work on speaking out and anyone working with us needs to know that this is how we operate currently.
