When starting from Tandem Couples, pass 
Left-shoulders
    with the other dancer in your Couple.
    This is because 
Trail Off is a Cross Peel Off: Leaders
    do a Half Sashay then Peel Off as Trailers 
step forward if necessary do a 
    Half Sashay then Peel Off.  Of course, when dancing, don't 
    abruptly do a Half Sashay 
then Peel Off.  Instead, blend the
    Half Sashay and Peel Off into one smooth movement.
