     Every kid wishes to be an adult. But now as grown-ups, some adults find they cannot leave

childhood behind. They become "kidults" (kid+adult). Being a kidult has become a lifestyle-choice

among young people across Asia.

      Some kidults collect toys they once played with.  Hello Kitty, Garfield, and Snoopy have many

adult fans around the world. It is not unusual to see a 20-something woman with a big, Garfield-shaped

cushion on her sofa or a Hello Kitty mobile phone accessory(附属品).

      Other kidults still enjoy children's stories and fairy tales. For example, Bloomsbury even published

the Harry Potter novels with an adult cover. That way, no one else on the subway will know that an

adult is actually reading a children's book!

      "Kidults can be like vitamins to society. Adults who value their childhood and hold on to pure,

child-like emotion may be needed in such a rough and dry society," said Lee Sojung, professor of

Foreign Studies at Hankuk University(韩国外国语大学). He added that kidult culture may fill the

generation gap between adults and kids. It could give children and their parents books, movies, and

cartoon shows to enjoy together. He may be right.

     Tim Greenhalgh, a professor, explained that some kidults just refuse to grow up. They value

childhood because life in a busy and stressful city frightens them. Kidults would like to forget their

age and openly show their fear of society and adulthood.

A. Kidults can't give up their toys their childhood
