I woke up in a good mood so I'm making more soft andreil headcanons
They go for walks on hiking trails when fall arrives and the leaves change color, using the chill of the air as an excuse to walk closer to each other, talking about whatever is on their minds until they circle back home.
Neil's lips are constantly chapped and it annoys the shit out of Andrew because they literally have so much Chapstick but Neil refuses to use it. So obviously, Andrew has to put Chapstick on his own lips and kiss Neil to try to get him to use any and yeah, Neil totally knows what he's doing and he's incredibly smug that it works every time.
Andrew starts humming. It's just a noise to fill the silence, quiet and deep with a different note every once in a while, and it's a nice sound in the otherwise quiet of their home. Neil especially loves feeling the vibrations through Andrew's chest when they lean against each other and it soon becomes comforting to them both.
The two went on a pottery date and it was kind of a disaster. Neither of them were able to make anything functional other than a lumpy bowl that Andrew tended to put candy in. But about a month later, Neil gives Andrew a giant mug painted sleek black, and he's so excited and smug about it because he went back and learned how to make it. It quickly becomes the only mug Andrew uses for cocoa, saying that it's the only one big enough.
(Neil got the idea right after they came back from their date and the whipped cream in the mug Andrew was using completely spilled over the side. He made plans to return to the pottery shop the next day)
They go roller-skating and they're both really good at it. They end up doing laps as a mock race, completely disrupting everyone else at the location, and as a result are asked to leave. They keep trying to find roller-skating parks to finish their race but keep getting kicked out of every location they go to.
They're both unbearable when they're sick. They both deny it until they can't and will either complain the entire time or be completely silent. Andrew hates swallowing pills so Neil will go store to store to find him some liquid Tylenol, and despite hating tea with his entire being, Andrew will painstakingly make sure it's perfect to soothe Neil's sore throat.
They literally only have one wardrobe. Andrew puts on Neil's sweatpants and sweaters and will grumble complaints about how he could possibly stand wearing it, it has holes in it and the hems are so worn and there's a stain, Josten, but none of this stops him from wearing the clothes.
Neil is the best baker between the two of them. He has endless patience for it, measures everything perfectly, and prepares everything to perfection. Despite this, he doesn't bake unless Andrew sends him a recipe, or unless it's Andrew's birthday, which is slightly annoying but also makes every treat so much more worth it.
They write little notes to each other. At first it's just notes from Neil with a time written below a simple 'going for a run', but one day Andrew writes a percentage on a note left behind and it just escalates from there. Most of them are kept in Neil's new binder.
