Oh, happy to tackle these two ο(=•ω<=)ρ⌒☆
falls asleep on the couch
Nerdanel. This is only because if Feanor is going to fall asleep somewhere he shouldn't, it will be his workbench. Both of them are devoted to their craft, so it's not unusual they wear themselves out, and Feanor especially is terrible about pushing himself well beyond the norm of sleep deprivation to work on something.
makes friends with the neighbors
Nerdanel, only because it definitely isn't Feanor. Feanor does not care to talk to their neighbors, he doesn't want to hear from their neighbors, he does not want to be disturbed by their neighbors. Fortunately, as they live in the royal palace, their only real neighbors are his family. Unfortunately, he does not get along with most of his family.
Nerdanel isn't especially gregarious either, but she can at least manage a surface level of politeness. But there are reasons she's not close with Anaire or Earwen.
is the adventurous eater
Feanor, because he'll basically eat whatever you put in front of him if he's looking to get back to something else. The only time he really whines about what he's eating is when he's being petulant. Nerdanel is not generally an adventurous eater; she has a few stock meals she makes and rarely ventures outside that because it's just easier to do it this way, and she's not a fan of cooking.
hogs the covers at night
I want to say Feanor, and also sakasakiii has a hilarious comic about this.
forgets to do the dishes
Feanor, although it's not so much that he "forgets" as that he has other things to do, and they have seven kids--there is definitely someone else whose time is less valuable who can do the dishes. But not Feanor. He's busy.
Needless to say when Nerdanel ends up doing several days' worth of dishes, she is less than pleased.
When Nerdanel goes off about the state of the kitchen, all seven boys will complain that no one told them they were supposed to do the dishes! Jeez amme, are they supposed to read minds?
tries to surprise their partner more often
Feanor. He makes stuff for Nerdanel all the time, so she's regularly getting gifts "just because" and even though a lot of it is jewelry and she doesn't wear a lot of jewelry, she keeps it all. Often, he inscribes something on what he gives her, so she hangs onto it for that.
He's also more spontaneous than her in general and more likely to pull her out of her workshop or some artisans' meeting as if there's something important going on, only to cajole her into going riding out past the city limits or going swimming or otherwise skipping out on their responsibilities.
After he left Aman, she didn't know what to do with it all, and ended up having several cupboards solely devoted to things Feanor had given her that she couldn't bear to sell, and some of it she destroyed when feeling particularly aggrieved.
leaves dirty laundry on the floor
Nerdanel. If she's worked especially late or is just worn out, she'll strip off her work clothes and leave them where they fell to go wash and change. Feanor regularly picks these things up for the laundry, but he doesn't mind doing it.
stays up til 2 AM reading
Feanor. He is the absolute worst about getting sucked into whatever he's doing and completely losing track of time. He has definitely worked straight through important events before (he should consider himself grateful Elves stop counting birthdays after they reach the age of majority, and don't celebrate annual memorials like wedding anniversaries). Fingolfin more than once has had to run down and pull Feanor out of the forge to be present at some event the crown prince is supposed to be present for (not that showing up covered in grease with his hair a mess is winning him big points with Finwe and Indis, nor is the failing to pay attention because he's still working through schematics in his head).
Nerdanel regularly has to go remind him to actually get some sleep.
sings in the shower
I don't think either of them is huge on it, but between the two of them, probably Nerdanel. Either of them is a lot more likely to do this if they have one of the babies with them, but I just don't see Feanor as a big singer, at least by Elf standards.
takes the selfies
Feanor. He's not obsessive about it, but he would definitely pose with his latest works in progress or creations to show them off. Once in a while he'll take one of him wearing jewelry he made, which is ostensibly the reason for the photo. Sometimes the kids pose with him.
Nerdanel might take pics of her works too, but the most you're likely to get of her is her reflection in a window or a hand or foot as she tries to get a good angle on the sculpture. She does show up in the selfies of other Finweans.
plans date night
Feanor. Nerdanel definitely does not go in for date planning. She is super casual about dating, so she was always kind of blown away by the stuff Feanor would plan for them, and this had a role in his winning her over. He definitely puts together some pretty extensive date night activities and he feels pretty good about himself when he manages to impress Nerdanel so he has incentive to keep it up.
