What a poignant story. As a teacher, I've had a few of these, where you had absolutely no idea that the student was feeling a particular way and then at the end of the year you'd get a long thankyou letter (because often having the courage to speak face to face when you're young is hard) about the shit they'd been going through and how something you said or what you did helped them enormously. Even years later I'll get an instagram DM thanking me out of the blue.
I didn't realise Finland had such a high rate of suicide.
We each make impacts on others and while we might not see the effects, someone might feel them for years to come.
It probably aligns with the high percentage of alcohol abuse too.
