her apartment unit has 3 floors, with an elevator connecting it allthe elevators go up nine floors and also down to the basement, which i assume that with just a button, you can go directly into the houses of everyone above and below you, and the elevators also go down to the lobbyPlus, there is only one elevator in the lobby, and since Freddie's house is beside hers, that means he has to have a whole different elevator system too, and that would be really expensive.I have always wondered this, since it invades privacy, and it just doesnt seem normalIm wondering if there are any other apartment buildings that use this system? or if it is different then the way i saw it/explained it, please explain how it really is.
