okay, i wish i had that second one irl because it sounds like perfection. how about a mixture of both? right now i have her as a transplant to moved to maine as a kid and left for college before coming back for some reason. we could say they went to the same hs but never connected and both wound up in nyc for college? one of them read a listing for a roommate, went to check it out, and they had a "do i know you from somewhere?" moment before becoming roomies. now they're neighbors because they're used to each other.
