Ageism

something especially seen in older childhood/teenage/youth stages* (when ur mostly supposed to interact/be with people exactly/close to your age be it as friends/lovers unless if ofc the personalities don't gel or they're abusive (god alone knows what these terms really mean) literally anyone else older or younger is either ur parent/much-older-sibling-cousin/mentor/guide/teacher or your son/daughter/pupil/much younger sibling or cousin (regardless of whether you actually are/have one or not)** older 50/60 single men tend to 'have their way' with youth/above 18 women due to the fiction/filmi star effect (although even this is increasingly rare and unpopular/scrutinized irl) (here nevertheless primary gender dynamics still play a big role)
