I did a search and couldn’t find this covered.
On Extreme Makeover Home Edition, when the family comes home, the house is hidden behind the bus once the family gets out of the limo. However, when the family is coming up the street or road in the Limo, how are they kept from seeing out the windows before they get behind the bus? Do they black out the windows of the limo? Or do they blindfold all the people in the limo? Or does the family just pretend they didn’t see anything?
