Our characters are college classmates, we live in the same dorm hallway but barely know each other (maybe it's the beginning of the semester). We arrive at the shared bathroom we share wearing only towels, since we're each here to take a shower - a rather awkward way for us to introduce ourselves, but so be it! It just so happens that all but one of the showers are currently in use. This is a problem for us because each of us would come to the bathroom to shower and go to class, and we need to be on time for the exam!
