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!”
Similar to this: telling someone with ADHD “stop letting yourself get distracted”
Or to someone with anxiety:
“Just don’t be anxious!”
🫠…
“But it’s not actually scary!”
Yes, I know, that’s why it’s a disorder and not just being a reasonable person who’s afraid of frightening things!
