     Recently a really strange thing happened at Wuhan Liangdaojie Middle School in Hubei. Over 600
Junior 1 and 2 students at the school took part in a "caring for an egg like a baby" activity. They were
asked to keep an egg close at hand for a month without breaking it.
     "It's hard for parents to bring up their children but many students take their parents' love for granted.
(把…当作理所当然)," said Liu Kang, the school's director. "We wanted them to learn that lesson by
taking care of an egg as a baby."
     Li Mingxuan is one of the students. His egg didn't break during the month, but he felt exhausted. "You
had to put so much attention to it," said the 13-year-old boy, "I now understand how much my parents
have done for me. I'll prepare them a glass of milk to help them sleep better every night."
     Not everyone was as lucky as Li. More than 450 of the 600 students broke their eggs.
     Yan Yueming broke his egg in just five days, which made him very frustrated. He said, "I can't imagine
how sad my parents would be if there was something wrong with me, their 'egg'!" I want to return their
love and I'll help them with chores every day." promised the 13-year-old boy.
