Really?

I recently had a heartfelt conversation with someone very close to Kelly.  He spoke about the bewilderment he often feels when reflecting upon the fact that she is gone.  I understand.  He commented that occasionally he will look over at his roommate, tilt his head and exclaim, "Really?".  One little word representing the mind-boggling thought - Did all that craziness actually happen?  Then laughter.  Again, I understand.  Head tilt.  Really?  Laughter.  A confused kind of laughter.  Releasing stress.  Helping the body cope while the brain keeps trying to make sense of something that makes no sense.
