I hate it when guests just decide to come over without even giving a call
In my country Serbia, that is considered a completely normal thing and everybody is doing that...
But since the last year I've been living in Germany and here it is not considered a normal thing... quite opposite it is considered to be very rude...
Once I called some people to ask if I could visit them that day and they accepted, but then politely pointed out to me that next time I should call them at least 1-2 days in advance!
I hate Nightwish
