when a friend changes their name, i dont have any issue with the switch. their old identity basically disappears, right? straight up I Do Not See It style
but if that same friend's deadname is shared with another friend's name? i'm stuck forever. i'm like oh, ive got two friends named david, cis guy and..... and i just draw a weird blank until i remember
anyway this is how i know that cache invalidation is truly one of the impossible problems
