Finland is a country with many strange and exiting habits that can confuse anyone who is visiting there.
To help you, there are few things you should know:
1. If someone offers you rye bread or a Sisu-pastille, eat it no matter how bad it would be ( because they are Finnish folkfood )
2.Only married people and relatives/close friends touch each other in public, because Finns are very afraid of touching.
3.If you´re in Helsinki, don´t praise Turku ( Turku is the old capital of Finland ) and vice versa.
4. You go naked to the sauna and it´s a thing you don´t have to worry about ( women and men go separately to the sauna of course )
