如果孩子说谁交了异性朋友;或者父母已知孩子有了知心的异性同学,可以这样告诉孩子:“你见过蓝天上的白云吗?清晨起来,看见蓝天上飘着白云,多么纯洁、美丽,令人喜爱;但是等到中午放学时再抬头看,清晨那朵白云不见了。青春期少男少女的友情,就像蓝天上的白云,美丽而脆弱,诱人而易变。”对经 If the child said who made the opposite sex friends; or parents know the child has the knowledge of the opposite sex, can tell the child: "Have you seen the white clouds on the sky? In the morning, saw the blue sky floating in the clouds, how pure, beautiful , But it was not until the middle of the day after school, when the white cloud disappeared in the early morning.The friendship between adolescent boys and girls was like the white clouds on the blue sky, beautiful and fragile, attractive and changeable.
