1. Swedes love their coffee. Few people drink as much coffee as the Swedes, they are highly ranked worldwide when it comes to coffee consumptions. This goes hand in hand with their daily Fika traditions. Coffee is fostered through a tradition called Fika, in which anyone can participate and meet for coffee, tea and often something sweet on the side. Fika is usually enjoyed on a daily basis.
2. Queueing is a common thing in Sweden. Wherever you go you will be forced to be patient and stand in line. Many places have ticketing systems, so once you grab your ticket you will patiently have to wait until your number is shown or called out before you can proceed to the counter.
3. Swedish people speak great English. Chances are you even get away living in Sweden without learning a word of Swedish. Swedes are widely rated as world number two at English as second language.
