"Do you ever get lost in this house?"
It is a large place, with some twists and turns, ex cetra but I built them and I live here and I am open now for the last 25 years!? If I get lost here, please don't send any search teams looking..."DUH??"
(Just patiently wait for me to begin stinking, then come looking)
"How many rooms are in this house?"
I say:"All of them, except for the rooms left outside?"
Like the big tourist cave when the workers get asked :"Is all of this cave underground?"
I would say," Yes, except for the part that sticks up out of the ground 110 feet in the air!"
