     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.

     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.
