shops for groceries: This is something they do together, actually. Trip is the one who feels like it's necessary to write a shopping list, but is also the one who impulse buys. Melinda on the other hand finds this completely unnecessary, but she only ever gets what they need.Trip makes up for this by occasionally throwing in a a just-for-fun/pampering purchase in the cart for her.
kills the spiders: Ok, so May once shot one with an icer and there is now a big hole in one of the walls in their apartment. She's not allowed to kill spiders anymore.
comes home drunk at 3am: Neither of them are the type to come home drunk or go out and get wild drunk. Also, they usually drink together these days. There is exactly one exception for both of them: For Trip, it's the anniversary of his partner's death. For May, it's the anniversary of Bahrain. They're both total wrecks on those days. Quiet wrecks, but wrecks none the less. And then the other doesn't drink at all, so as to be there for the other person in the fullest extent possible.
makes breakfast: Trip does. It's a tradition he started after the first night they spent together. He doesn't make breakfast every day; sometimes they make it together or sometimes it's something simple that doesn't require prep. But he still makes sure to spoil her from time to time with breakfast in bed. :)
remembers to feed the fish: They are both excellent at this. The only problem was when they first got the fish, they forgot to communicate about this. Their fish got overfed a few times at the beginning, because both of them assumed it was their responsibility.
decorates the apartment: Neither of them are big decorators?
initiates duets: This is Trip completely. He starts singing when they're lounging around the house. And May ignores him at first. But he comes up beside her and bumps his hip against her's and grins that solar flare smile of his and soon May is singing along inspite of herself.
falls asleep first: This is a tough one. They're both specialists, which means they trained to be alert at all times and sleep only as much as necessary. They can fall asleep in short bursts at the drop of a hat when they need to be ready for a mission. Otherwise both of them struggle some with insomnia. So, mostly they trade off being the one who falls asleep first.
