In Standard Swedish, the word ”fara” is used solely when someone makes an extended trip. You can, for example, ”fara” to Australia. In the north, however, you use ”fara” for any kind of trip, whether it’s to the mountains, to the office or your next-door neighbor.
People of the North generally do not care all the much whether the grammar is one hundred percent adequate or whether the one you’re in dialogue with is slightly offended. If you don’t feel like doing something, you let them now by bluntly saying so: ”jag ids int” (I cannot be bothered).
