So that night, Duan Gen slept in Xiajun's room.
"Right, I got you a fold-up mattress from the old lady downstairs," said Xiajun, nudging the musty thing with his foot. "Just put it against the wall."
"Like this?" asked Duan Gen as he flipped the mattress open. "Am I doing this right?"
Xiajun gave a nod. "You've got your blankets and stuff? I have a double bed so you can just take my pillow."
"Yes, the woman downstairs gave me one, since she knows I'm staying with you," Duan Gen said, pausing. "Have you had dinner yet?"
"I'm not hungry," said Xiajun as he flopped down on his bed. "Though you can see if they have something in the kitchens if you want some dinner. Or I'll lend you some money and you can hop down to the convenience store around the corner, whatever you'd like."
Duan Gen shook his head, looking embarrassed. "No, that won't be necessary. I'll go see if they have some bread or something. Thank you, though."
