Why Finland is so kind to Russia?

The distance between the two countries is close and Russia is friendly to the Finnish people.

Finland has three neighboring countries, namely Sweden, Norway and Russia. Among them, the border between Finland and Russia is the longest, reaching 134 kilometers. Therefore, Finland has always attached great importance to its relations with Russia and tried its best to do a good job in friendly relations with Russia.

Compared with the early Swedish rule in Finland, after the Russian Empire, the Grand Duchy of Finland has more autonomy, and the parliament can decide most internal affairs. Finnish has also resumed its position as the official language, and Finns no longer need to speak Swedish. According to Wikipedia, most Finns are satisfied with Russia.
