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!”
How much is it worth now?
Sold it 5 years ago for somewhere in the 700s. So ultimately it turned out okay. But there was an extremely awkward period where I had to move out and would have sold if it wasn’t underwater. I wound up becoming a landlord for several years which I wouldn’t have chosen and felt pretty scummy but it did save me in the long run.
