What do you think about me arguing over a window?
Why would you debate about a window?
Because my roommate doesn't want to keep the window open. We have this argument almost once a day.
Arguing almost every day over a window is going to be very stressful for anyone. Instead of arguing about the window, reach an agreement over it. Perhaps allow it to be open at certain times of the day?
Why should I do anything? Windows are important for students.
Compromising with your roommate about when the window should be open is the wise and less stressful thing to do.
