My Finnish gf told me that the police in Finland is so reasonable and human, that often they will stop by just to check in if everyone are safe and well and if anyone needs assistance. She mentioned countless of times she was with her international friends partying, or doing sauna or skinny dipping in the lake, often all the three things in the same night of course, when her friends got nervous when the police stopped by, and she was like "ahh no, don't worry, they just want to check if we are all okay".

Police asked if they are all safe, nodded and wished them a nice party.
