mike obsessed over space with dustin in 4th grade and immediately became friends with him even though mike takes a while to open up to people usually
mike was an ao3 pioneer by writing short stories about comic characters he'd read about in his notebooks in class
mike took the party on an expedition to the comic store and was forced into reading wonder woman comics by max and el (he liked them)
mike used his science fun facts in campaigns
mike picked up the guitar as a hobby in the time between will moving and joining hellfire since his dnd wasn't really available at the time (he loved learning his favorite songs)
mike had blurry vision in high school but refused to tell anyone because he thought he looked ugly with glasses (he looks adorable)
mike tried to indulge in the visual arts because all the byers do some type of visual art (he sucked at drawing and photography but he was really good at crafty stuff like el (he made all his minifigures himself))
honestly prefers his neat sweaters and collared shirts over more alternative clothing because he prioritizes comfort over fashion
neat outfit but his socks are always mismatched
feels pretty in maxi skirts. but he doesn't wear them often because he always finds a way to trip on them
he refused to style his curls for years
one time (pre-s4) on the way home he grabbed and threw dustin's bag onto the branch of a tree and watched as dustin tried to get it down with a stick (he could've helped since he's tall but he found it too amusing)
he didn't think much about the color blue but will told mike in kindergarten that he thought mike was very blue so when his mom asked him what color he wanted his walls he just chose blue
mike has a big scar on his face from billy and he hated it so much until eddie said that it made him look like a warrior and he's rocked it proudly ever since
^^ although it took a while for him to like it because he doesn't like most of his features and it takes him a while to actually accept them
in college, whoever he rooms with does the laundry because he tried to do it once and almost died because he tripped on a step and couldn't catch himself because he had the laundry in his hand (he does most of the other chores to make up for it) (he's very specific about it being even but he complains about it regardless)
he used lucas's basketball games to explore his sexuality but he never told lucas that's why he started showing up (wheelclair)
usually lets out huffs as laughs but when something is funny enough he starts cackling and its always high pitched and sometimes his voice cracks (he locks in immediately after that)
good at writing stories, horrible at writing letters
does cliche romantic acts for his partner because he gets worried that he doesn't show his affection well enough (even tho he's clingy asf)
his love languages to give are physical touch and acts of service and his love language to receive is words of affirmation
ok idk if i'll add more but do u guys agree with this
