leaves their dirty clothes on the floor: Makoto is more likely to drop her clothes to the floor while she takes a shower at which point Jadeite will steal them to toss in the laundry and mock her for being the sloppy one. (this marriage sounds highly dangeorus)
forgets to run the dish washer: Jadeite is more likely too, at which point Makoto mocks him.
pumps gas for the car: Makoto does it because Jadeite is still useless with cars.
drives when they’re going somewhere: Also Mako.
rearranges the furniture: Jaddeite. Sometimes he does it while Mako is sleeping and then pretends it's always been like that to fuck with her. She always figures it out and rolls her eyes.
falls asleep with the TV on: Jadeite! Makoto has an instagram of pictures of him in increasingly embarrassing or cute items while he sleeps. The list so far includes, googly eyes, fake mustache, kitty ear headband, and with a propped up plushie on his chest.
gets to use the bathroom first: Jadeite ALWAYS steals bathroom.
decides the temperature for the ac/heater: Jadeite. He's a wimp in the cold.
sets up holiday decorations: Both! It is one of the few things they agree on - Mako loves decorating, and Jadeite is competitive enough to want to help be the best.
leaves the lights on: Usually Jade. Mako watches the electricity bill closely.
uses the bathroom with the door open: Neither!
fixes the plumbing (or calls the plumber): Either Makoto knows how to fix something or the call a plumber, Jade is pretty useless here.
