if only the basis of being name twins was enough to go off of lol! except charli is just the "american" name she chose after learning "damn, no one can pronounce my actual name..." so she doesn't even bother with that anymore. they do sound pretty similar though and i can see them getting along! does charlie attend many college parties or anything like that? i'm not 100% decided on where she's studying actually so it's possible that charli tried to sneak out and attend a party under her parents' noses, they could have bumped into each other there?
