where did you hear the second part?
please look at the diagrams online (sadly, needs IE, cannot be viewed in firefox or opera or any other browser):

notice the little stairs there on the 5th floor, left? that's because there's a few steps between levels (quad isn't one big level structure) - the hallway goes all the way to rodney, where it ends in a suite entrance.
as you see, that ef smith 5th floor stairs (not a full floor transition, again, just like 5 steps?) connects to wilson 4th floor... which connects to morgan 4th floor... which connects to the memorial tower's ware library... which goes into ny alumni 4th floor, in fisher hassenfeld.
seriously i'll walk over there myself and take pictures and put them up here if it'll soothe your fears.
and no, hallmates are never necessarily your closest friends.
and the activities in which you participate / classes that you take will expand your horizons far beyond your living situation.
please, please, stop worrying about this silly little quibble.
