I'm not sure about that. Friends and family members do happen to remember something I or someone else said or did even years ago. People DO watch and pay attention, and often judge.
Which reminds me that verbal and emotional abuse from parents and close family can have a severe impact reaching far into adult-hood. You can't help having internalized behaviors build around trying to avoid abuse. You can rationally understand that maybe most people aren't judging you like that, but you're also keenly aware that the world is filled with enough who are and with strangers you can never tell who's who.
yes, but that's people you know. Not random strangers at some random party. Talking to strangers is "easier" when you realize that what they think about you does not matter.
