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!”
I’ve realized the verb tense in my original post is misleading. I’m also in my 30s, and was expressing the opinion I had when I was 19. I have a well-established life now, with friends and family and purpose. But I’m not going to at like the experience didn’t shape me either.
