So when the couple decided to adopt three years ago, they chose to fake a pregnancy, as many adoptive parents here do. The couple moved, and the husband, now 43 and a real estate agent, switched jobs. The wife, an employee at a telecommunications company, began wearing maternity clothes over a special pillow, made by a company recommended by the couple’s adoption agency.All was going well until a colleague the woman had confided in spilled the secret to a supervisor.“I was so hurt and embarrassed by that experience,” she said. “I would like to adopt a second child, if only to go through the experience in a proper manner this time.”Given the bias against adoptions, some couples who are initially open become more guarded as their children grow older.Yoo Hae-yon, 48, has told relatives and neighbors that his two sons, now 4 years old and 18 months, were adopted. But he has since become worried that the boys will suffer in a society where television shows typically portray adopted children negatively, as schemers who end up damaging families.“My sons haven’t been teased yet, but that will be a possibility in elementary school,” Mr. Yoo said. “So once they start school, we won’t disclose their adoptions. And in junior high school or later on, we’ll let them decide.” - www.nytimes.com
