here are some basic rules for guys when girls have their periods:
do not make eye contact

stay at least 10 feet away
do not make any conversation if you would like to keep your face in its current state
guy: hey babe
girl: if you dont back up by the count of ten, i will rip your nuts off!!!
guy: ok hun, bye
guy: i just broke the period rules
