In this case Finland actually takes care of their people and homelessness isn’t a problem there. They’re just really polite introverts who I might guess prefer sitting alone as opposed to on a bench close to others.
Source - my introverted niece met a Fin, fell in love, moved to Finland and is in absolute heaven. Her husband has visited the States a few times and is always overwhelmed with the casual social interactions with strangers in public.
Or adults!
I used to teach massage at a vocational school, and for multiple reasons had a “no phones” policy on the classroom (distraction, exposed body parts, and others.) I could have ignored it during lectures except that the overlap of students on their phone and the ones asking to re-explain information or just lost as to what they’re supposed to be doing was nearly perfect.
