Teacher differences notwithstanding, one homeroom is the same as the rest in function. All teachers have a handout they have been asked by the school’s counselors to give to each student. You receive one, and are requested to fill it out.
You notice that people are chatting with each other about the sheet. It’s apparently a pretty good way to get to know the students around you! But first, you’d better fill it in.
(Post your result here. If you want, roll 2d6 and add your Social stat to determine if you find someone around you who wants to talk with you. This may or may not be another player character in your room.)
