Adjustment of Status - I-485

I had my interview today....the IO was not friendly in any form, he separated us...he called me in first, he asked all sort of questions like, my place of birth, what i do before coming the us, the full name of my wife, whether he had been married previously, her son's name, does he live with us?, who proposed, when did i do it (date), how did i proposed, what is the size of our bed, how do we sleep,who sleep on the left or the right side of the bed? what did we do on last Christmas, date and place of marriage, how many people were at the ceremony, who administered the wedding, how do our house looks like, what does my wife do for living, her work schedule, how does she get to work, does she has a car (no she doesn't) etc. When he was through with me, he took me back to the lobby and asked my wife to come, he asked same question, my wife got almost everything right except for the part i said she cooked and stay home with me on Christmas, i forgot she later went out with her mum that day . However, to my major suprised, when he completed my wife session, he didn't request to see me, he just told my wife that they will get back to us in 7 to 10 business days....no other ref or any information....just that....please do anyone know what that means, i am nervous. We were not told about 2 yrs conditional GC or anything like that.....
