Why do people say “tell me about yourself”when they won’t give a shit a few days later?

Because we are bored.

Maybe they don’t like what you’ve told them? Or they are mental cases . Or have other issues. Don’t take it personally people are flake modes and not very loyal sadly.

Curiosity. It's not always about caring, but about seeing if there's anything in the answer they can work with

I don't know why, but that's the way it is mostly.

Can't think of shit to say

Tell me about yourself

They are interested at the time.
