This was kind of planned between my wife's daughter and I. I knew my wife had to go on a business trip with her boss and she would only return the next day after dinner and I had to pick her up at the airport. So I called my step-daughter to tell her the news and that if she wanted to "surprise visit" us she should arrive a day before her mother leave, and ask her if she could stay there for two or three days because she had two job interviews to go to. This way wouldn't be suspicious. Well, this was how we spent all morning...
