19. Your roommate insists on sleeping with the light on. You yourself not only cannot recall a time when you did this, you also find it to be an insanely hard condition to sleep under. One day, you decide to buy him a night light. Something that shall at least allow you to get some shut eye, whilst at the same time enabling him to see what's directly around him. Instead your roommate loudly complains about not having his precious lightbulb vision, and ends up bursting into yet another crying session.
