甲、乙为夫妻(户籍所在地为H市大河区)，二人于2004年10月以150万元的价格购置H市理光区彩霞路一套房屋，后因房屋距离工作单位较远，夫妻商议决定将房屋卖掉，但未找到合适的买主。2005年2月初，乙赴外地出差，住H市文化区的丙找到甲，称过去已看过该房，愿以160万元价格买下，甲不同意；双方经协商，甲决定以170万元价格出售该房。次日，丙支付给甲100万元，甲遂将钥匙交给丙。因产权证被乙存放在单位，所以甲提出待丈夫出差回来，即办理产权过户登记，办完手续后丙再付70万元。同年7月初，乙从外地返回后得知该房屋价格已经上涨，遂找到丙，要求增加10万元价款才能去办理过产登记手续。丙不同意。同年8月10日，乙以200万元的价格将该房卖给了丁，并在8月15日与丁办理了房屋过户手续。后来，丁找到丙，要求已人住的丙搬走。丙遂到法院起诉，告乙、丁侵害其所有，并要求法院解除乙与丁之间的房屋买卖合同。丁反诉丙，要求丙搬出房屋。

One school night this month I walked quietly up to Alexander, my 15-year-old son, and touched his cheek gently in a manner I hoped would seem casual．A year ago he would have ignored this disturbance but now he reacted impatiently and leaned back to his computer screen．

I made a mistake: breaking into my teenager's personal space. “The average teenager has pretty strong feelings about his privacy," Lara Fox and her friend Hilary Frankel told me. Mr．Frankel and Mr．Fox, both 17, are the authors of Breaking the Code, a new book that seeks to bridge the generational divide between parents and adolescents．It is being promoted by its publisher as the first self-help guide by teenagers for their parents, a kind of "Kids Are From Mars, Parents Are From Venus" that explains the language and actions of teenagers．The girls dealt with issues including hanging out late, money, school pressures, smoking etc．

Personally, I welcome their opinions．The most common missteps in interacting with teenagers arise from the war between parents exercising their rights to know what goes on under their roof and teenagers firmly guarding their privacy．Teenagers can be quick to interpret their parents' remarks and respond with anger that masks their vulnerability （脆弱）. Ms Fox said, "What we want above all is your approval．Don't forget, no matter how much we act as if we don't care what you say, we believe the things you say about us．"

Nancy, a New York child-raising expert said she didn't agree with everything the authors suggested but found their arguments reasonable．"When your kids are saying, ' You don't get it, and you never will, ' there are lots of ways to respond so that they will listen and that is what the writers point out．"

" My parents helped me see that, " Mr．Fox told me, " even though they used to stay out late and ride their bicycles to school, times have changed and the way parents educate children is different．These days there is a major fear factor in bringing up kids．Parents worry about their child crossing the street．" The writers said they hoped simply to throw light on teenage thinking．
