As someone whose Tragic Backstory has resulted in me having an often scorched earth relationship with past friends/acquaintances (meaning, I have either deliberately or accidentally burnt almost all of my bridges-- I do not keep up with anyone I served in the military with on purpose and same with my retail job while I was school-going, I was homeschooled and have no traditional high school friends, I went to evening college as a busy adult and made no college friends, I nuked the site from orbit re: my own family, etc etc), I just had the fascinating experience of catching up with someone I hadn't spoken to in many years, realizing we don't have much in common anymore, and that being a fine and normal thing
anyway just kind of a nice human experience to be like hey! we used to connect deeper, now we don't, that's okay and have a great time
