I searched the entire house and still couldn't find him!
Did you think he was in the house?
I have a feeling he is in this house, but I can't find him. I asked my wife to show me the way, but she led me into the wrong direction.
I understand.  If someone is missing you should look everywhere not just inside the house.
I don't care, I will look at my neighbors house right now.
Okay that is a good start. Maybe you should alert the authorities so they can help you search a wider area.
