my autistic sirius and reg hc made me think about how regulus would be like. extremely into lists and schedules and make one for everything he needs to do for every day and he has to follow it exactly. whereas sirius would hate lists and schedules. abhors them.

which means when they were kids and actually hung out, at least a little, regulus would be there with his schedule for the day trying and failing to get sirius to follow it because yesterday sirius said they would play the piano together so regulus slotted that activity down for 11am but now its 11:05 and sirius doesn't want to because he's just noticed that one of the chairs in the parlour is wonky so now he has to check all the chairs and take the wonky ones up to his room and take them apart and use the wood to make a pirate ship.
