I interpreted GP's message as "We used to lean-on and learn-from our friends, families, and coworkers, and insodoing we ourselves improved in a symbiotic way".

The "job" in the speech example would be "hey Joe, can I run this speech by you?"

In that scenario, the friend would:

  * feel valued, 
  * connect with you, 
  * have something to do socially instead of "sooo uh whatcha been up to... uh... nice weather...", and
  * get to hone their own speech skills by critiquing in a safe environment.

Ok; That's good feedback. Job may not have been the right word. I admit I didn't pass my comment through an LLM, so thank you for helping me improve and push harder. ;)
