Is this story trying to tell kind people to mind their own business when helping someone??
So far, it seems more along the lines of realizing that even good intentions and actions that seem good in a vacuum can still really hurt somebody, depending on what they've got going on inside.
I mean, for a less extreme example, someone who's struggling with impostor syndrome is probably going to get more anxious if told "I'm sure you'll do a great job!" before trying to perform in a big event, instead of the intended comfort those words should provide. But the same expression that someone believes they can do it might help someone who's just lacking a bit of confidence. (There are even competitive folks who take "yeah, I'm pretty sure you can't do it, so just give up" as a challenge and perform better after being talked down at in ways that would crush people who lack confidence.) It all depends on the personality of the person you're dealing with, and it often ties into internal flaws people deliberately try to hide.
