The same with my sister in law, 37 not marry. On the weekend she doesn't has to go to work, she will stay up till whenever and the next day she can sleep till 5:00 p.m.(Yes, It is P.M)!!! Her mother says the same thing 個妹放假, let her sleep la. She only 返8個鍾既寫字樓工咋,都話好累,not even 體力勞動! She never pick up her dish after dinner, her mother does everything for her. The good thing is we don't live together, no eye see!!!
