Gene’s apartment isn’t dirty. He keeps it perfectly clean. It’s just that he goes through cycles of messiness, wherein his apartment will be without clutter for two weeks, and then one day he’ll inevitably be too tired to fold a load of towels and underwear, and everything goes downhill from there. The clean laundry in the hamper quickly overflows, taking over the armchair and then the top of his dresser, and if it’s already this messy, he might as well leave six half-finished books on the nightstand, too.
