I’ll go first: “You have to have children when you’re young,” told to me when I was in my late 20s, with no desire to ever have kids, and no means to support them, by someone divorced multiple times with at least one adult child who does not speak to them.
Also: Responding to “How do I deal with this problem?” questions with “Oh, don’t worry about it, it’s enough that you’re even thinking about it!”
Oh yeah even lifeprotips, if you go in the comments it’s just full of people grasping at straws to find the tip useless and upvoting each other’s cynicism
There was one: “If you want a fridge’s compressor to turn on and off less frequently (ie: if you sleep in the same room), fill it with water bottles to increase thermal mass” and the top comments were “Actual life pro tio: get an apartment with 2 rooms???”
I was like: are these people actually that slow?
The less there is to say about an advice, the less reasons you have to go write a comment. Therefore the people in the comments are often outliers
