-So many questions left unanswered.
-That bond, and real close relationship you had with that person.
-The feeling of comfort and trust you have with ONE special individual that you know is way different than the bond you have with friends.

-That guilty concious feeling of knowing that you had done something wrong to lead to this situation.
