They cook together. Calcifer keeps Sophie from getting distracted and burning things and Sophie keeps Calcifer interested with guilt trips until she’s done.
How often do they fight?:
Surprisingly little because it takes two to fight and they both lose interest. They each make their own sharp comment in an instant when they’re displeased, but that is the end of the thing. Generally, it isn’t each other they’re vexed with anyway.
What do they do when they’re away from each other?:
They manage just fine. Well, Sophie thinks she manages just fine and Calcifer thinks of the things they’ll likely have to help her correct upon on their return.
Who steals the covers at night?:
Sophie, of course, but Calcifer lets her and they don’t grumble about it. Calcifer always runs warmer than she does anyway.
Remembering depends upon how much attention one was paying in the first place. Generally Calcifer, though they’ll turn things into riddles rather than express the memory outright. Sophie.... is only selectively observant at best and her memory for most things is even worse. On occasion, though, she remembers (usually something Calcifer wanted her to forget.)
Neither are big cussers. Calcifer is precise with their words and Sophie only cusses with her eyes.
Who takes longer showers?:
Probably Calcifer, though neither is particularly used to long showers after living with Howl.
What’s their favorite place to go together?:
Outside. Sophie loves her garden, Calcifer loves fresh air. Everyone wins.
Who’s more likely to burn dinner?:
Sophie due to distraction; Calcifer due to spite.
Who falls asleep on the couch?:
Sophie, usually with sewing of some sort in her lap.
Who sings in the shower?:
If one of them has to, it would be Calcifer, but neither of them really do.
Calcifer plans (at the last moment), but Sophie prepares.
Sophie has always been an early riser, and it’s only gotten worse after the curse turned her into an old woman.
Who drinks all of the coffee?:
Who drinks all the coffee or who cleans the pot before it’s empty?
Who starts getting into holidays way before they should?:
Sophie stops short of cluttering the house with holiday-related decorations, as she can’t really stand to keep anything like that in storage, but she makes sure the house is tidy and the meals are prepared. At the very least, the house will smell like the holiday and its appropriate treats.
Who initiates the couple selfies?:
Howl. (Yes, we know he isn’t part of ‘the couple.’ That doesn’t seem to matter.)
Who forgets the birthdays and anniversaries?:
Calcifer doesn’t tend to track dates, so they’re the ones to forget. Sophie isn’t likely to notice until days afterward, though. Birthdays and anniversaries aren’t particularly important to her.
