21. Any routines one has that the other had to get used to (ex. morning, nighttime, sleeping habits)?
i think sirius has to get used to remus being up during the night. sirius can sleep anywhere pretty much immediately but i hc that remus has insomnia, so he's usually up reading or watching something or most likely playing a video game on his computer. sirius doesn't hate it, but whenever remus is having a bad insomnia spike he goes to sleep with an eye mask on and some ear plugs, just so he can sleep without being woken up. remus bought them for him actually, bc he felt bad, but sirius wants remus to do what makes him happy so he gets used to it quickly. remus is also, at first, not used to sirius' hyper moments when they start living together. he's used to a very quiet, calm enviornment so its a bit of a shock when he hears sirius belting out a song, blasting his music, or just running around the flat bc he's excited. remus eventually starts joining in which is cute. for jily, i think lily has to get used to how early james gets up to work out. she isn't an early bird by choice whilst he is, and she is always a lil grumpy in the morning when she gets jostled awake or hears james humming as he gets his workout stuff on. but he always brings her back a pastry and a coffee so its not all bad. and james isn't used to mess, nothing crazy but lily often forgets to pick her clothes up off the floor or hang stuff back up, theyve lost the house keys a bunch of times bc of this lmao, but he starts helping her out or buying a little bowl specifically for the keys, and a better hamper for their clothes, to try and help her out
