Manners

Meeting and Greeting

Greetings are casual, with a firm handshake, direct eye contact, and a smile.
Norwegians are egalitarian and casual; they often introduce themselves with their first name only.
In some circumstances people may use the honorific title "Herr" (Mr.) or "Fru" (Mrs.) and their surname.
You can wait to be invited before moving to first names although most people will start with this.
Shake hands and say good-bye individually when arriving or departing.
Shake hands with people on a first come first served basis.
In Norway where people greet each other by saying ‘hello’ or ‘good morning’, people in UAE greet each other in an Islamic aspect of saying ‘Alsalam Alaikum’ to mean may God and peace be with you as a means of showing love. More so, shaking hands, especially with the women is not allowed in UAE. But in Norway is allowed.

Dress code

Norwegians are notoriously informal, particularly in clothing. Norwegians don't usually dress smart for work and rather casually most of the time. Although some may dress up for a restaurant visit, casual dress is fully acceptable virtually everywhere.
Norwegians find it perfectly natural to wear sport clothes and rucksack anywhere.
Norwegians generally don't dress very formal. Blue denims are used everywhere. if you somebody with a fashionable suit and tie (in the midle of the day), it is probably a real estate or stock broker.
Norwegians don't hesitate to strip down to bikini or short pants in warm, sunny weather. Don't be surprised to see shoppers in bikinis and short pants only.
The dress code of the people in UAE shows respect to the Islamic culture; do not expose your body with tight skinny wears especially for the women. Men should wear official suits and women dresses which cover their legs and hands.

Traditional dress

The bunad is a traditional Norwegian costume worn by both men and women. It can either come from established rural traditions or have a more modern design inspired by historical patterns and cuts. Traditionallybunads represented the family home and the area people came from but now in the modern world where moving from place to place is a necessity, Norwegians wear thebunad tradition from the place to which they have the strongest attachment.

Today thebunad is worn for celebrations and special occasions. During the wedding season (May-June), you often see Norwegians dressed in theirbunads on Saturdays walking to and from Churches. Baptisms and Confirmations, Balls and Norwegian Constitution Day are typically bunad wearing days.

Body language

In UAE, people employ eye contact as a means of showing sincerity and attentiveness. But in Norway is used to show attentiveness (Walsh, 2010). It is considered unethical to admire your host’s item in excess because they may feel obligated to give it to you.
