i think it's important and beautiful to delineate between different types of idiots. i will use my own OCs as examples
shrimpgirl (shrimpgirl) ((her name is shrimpgirl))
thinks a lot but it's kind of like if someone's running train of thought was a nightcore music video of shapes and colours with no words
if asked to solve a math problem she would confidently do so. she would then be confused that she got it wrong
despite living in a nice apartment, she doesn't take advantage of little things like "the shower". it's not a slump or mental illness; she's just a stinky woman
very prideful and stubborn. doesn't like to be made fun of
would eat a cursed concoction for money
mirabelle cherry (vampire/blood demon)
doesn't think
if asked to solve a math problem, she simply wouldn't
despite hanging out anywhere, she keeps herself perfectly groomed and dressed up. maybe it's weird magic luck or resourcefulness, but she cares more about her appearance than having stable food or shelter
will beg to bite strangers for blood. would shake a vending machine for one chocolate bar. pathetic behaviour doesn't make her feel ashamed
doesn't know much and will ask questions when confused but will not listen to any explanations provided
would eat a cursed concoction for fun
