That night, after coming home drunk, the sister-in-law went straight to her brother-in-law's room instead of her own. And then that night, many emotions happened, happy: when the two told stories about the neighbors around, sad: when the sister-in-law said that her husband often went to work until the next morning, and... happy: when the wife was so drunk, she couldn't tell whether she was with her husband or her brother-in-law, and so... of course both were happy.
