Haha , Frank Llyod Write Never made a front door to any of his houses , you had to enter from the back or side . So we walked to the back door witch is hiddin inside a cave like porch . ( your never caught in the rain looking for your keys ) then we go in . the entry winds around a short hallway before you actualy enter the house .

Question: Why might one never be caught in the rain looking for keys , here ?
Answer: None of the above choices .Because the house did n't use keys to open the doors , it was electronic .There were n't any doors to open in a Frank Lloyd Wright house .Because this house had an unusual entrance that would block the weather .
