Some concepts that live in my head rent free:

Prince Florida picking DC up in a hug and spinning then setting him down and beaming  while talking about how much he missed him

California staring longingly at Texas

Mass glaring at everyone but the second Florida walks up to him his expression softens and he wraps an arm around Florida and ask him how his day was

New York who is rarely affectionate laying in bed with Cali one night and telling him how much he loves him while running a hand through his hair

Mornings where DC is trying to get ready for work while Cali is still trying to wake up
and DC gives him a kiss on the cheek and passes him a cup of coffee before leaving with one last "I love you!" As he walks out

Texas had Louisiana being more subtle with their affection but if you look close you can see it
-Texas waking Louisiana up in the mornings to tell him breakfast it ready
-Louisiana making sure Texas takes care of himself
-the small looks they share during meetings
-late nights cuddling on the couch when everyone else has already gone to sleep

Alabama and Ohio jokingly trying to one up each other in front of Indiana

Prince Florida when he's finally allowed to marry DC is 100% talking about him constantly
To the point where it's like that draw your otp meme and it's just
Florida, with an arm around DC: [excited] I love DC more than I love my mom!!
DC: [hiding his face in his hands because 'oh my god Florida we're in public!']

And now, me rewriting two canon that live in my head rent free

New York, dragging Florida into Mass' lesson room: It's not my day to watch him

New York: google it
Florida: [grinning] I can't read
New York, internally: you're so fucking stupid and adorable I love you holy fuck-
New York, out loud: fine
