Ethos: for ethos I would use the strategy of sharing person information from someone who has been here a while. I haven't yet asked around about this house rule, but I'm sure if I did I could find someone who has a distaste for it as well.
Pathos: for pathos I would use my own situation to appeal to the readers/listener's emotions. I have 3 friends coming up down from Oregon who wanted to visit me and other friends this summer. Part of their trip was going to be staying in my apartment (if my roommates were okay with it, which they were) for a couple days. Because of the rules they could still come down, but now they have no place to stay, which kind of ruins the plans.
Logos: for logos I would point out factors like the size of the room: the couch can fit 2 sleeping people comfortably, and the living room floor is more than big enough for three people; it shouldn't be a big deal of roommates want to have guests of the same gender over to spend the night- not enough to limit guests and not enough to tack on a $40 fine if said rules are not abided by; if all roommates are okay with it, the housing people shouldn't have a problem with it.
