my nd friend group has a protocol for this! if you think you already understand what the other person is saying, you just say “avocado”. then they either ask some questions to confirm or just say “ok but i wanna info dump anyways” and then it’s COLLABORATIVE info dumping!
Congrats, I too have a solid group of ND friends all exploring their condition and we have similar mechanism to acknowledge communication issues and trying to make them more palatable for the group in an honest, fair and kind way that brings us all up and doesn’t shut us down. I am incredibly lucky and I love my bros unconditionally too.
