what about selective invisiblity, where a person masks himself from only one certain individual, but everyone else can see him?
my friend seems to have mastered that ability. a group of us were messing around in a class and the teacher yelled at us to come over to the rest of
the group. he began to name off names, and named even the person hiding behind a post, but didnt say my friends name, even though he was front and
center. werid huh? and when we went over to the teacher he even asked us if we had seen our friend, so it wasnt like he just decided to let him off or
forgot his name. my friend has pulled this off more than once. any theoreys?
