ONE: comment with your character and preferences. is that ever not the protocol?
TWO: reply to others.
THREE: your character. that character. holding hands.
FOUR: comfort somebody! reach out for emotional support! keep a kid from running into the street! escape certain death, saving another hapless victim along the way! confess deep-seated feelings! get closer on a date! intimidate your opponent! ...hold their hand for no reason at all, since you don't l-like them or anything.
FIVE: this can be a gen meme. it can also be a romantic meme, if you're a filthy pervert. gross. how can you be so lewd?
