Spying On Neighbors

Me and Steeners look across a 5 foot gap into the building next door, 25 stories up in the sky. The apartment next door is always DEAD during the day. And at night, a white girl and black guy take their seats at desks and work at laptops. Then, an asian girl pops out and works at a laptop too on occasion. We think she lives there because we see her in the attached bedroom from a window next to our elevator in the hall. The lights are on practically EVERY night, ALL night. And every horizontal surface in the room is covered with stacks of papers and books. What do you think they're doing in there?
