<p>Although I probably won’t stay in a single sex floor, I disagree with the above poster in that I don’t think they are silly. For me - as a woman - it is quite a luxury to walk down the hall in PJs or run to the bathroom without a bra, given that there are considerably fewer men around. I, for one, have never lived in a house with men and as a result might feel uncomfortable in such a situation. For some, it can be an issue of safety; for me, it’s just an issue of modesty; still others refer to comfort or atmosphere. There are pros and cons, but I don’t think it’s necessary to degrade one option or another. I certainly wouldn’t appreciate a fully co-ed bathroom, but I understand there are people who don’t mind. I think the opposite should stand true.</p>
