Going on a Sunday ice-skating in the frozen sea to have a picnic in an island at -20 °C is a lot of fun.
Not being able to sleep in summer is fun… and Juhannus (midsummer) is a lot of fun, regardless of whether you spend it with family or friends.
Salmiakki (salty licorice) rules!
Piimä (sour milk) is evil.
I understand why Finnish has no future tense and no gender differentiation, but it has lots of words for sauna, for snow and for weird things like kaamos. Your reality determines your language, and vice versa.
To walk in the snow and the icy sidewalks… and only fell twice! One included such a nice ukemi that I didn’t break anything, heh.
You can have good friends without talking with them about anything.
