✹ About Saturday 12 July 1662 Dick Wilson on 10 Jul 2015 • Link British English and American English differ in counting "floors". A Brit enters a building on the ground Floor, goes upstairs to the first floor, and up again to the second, etc. A Yank enters on the ground Floor which to him is the first floor, then goes up to the second floor, and up again to the third, etc. When Sam has the roof removed and his house extended vertically, this could be confusing. Presumably, he follows the English system of counting floors.
