Why the difference?????

For the first time in my life, after all these years, I finally really, really took the safety of another person seriously.  I really cared.  I was really anxious to know if they got home safe, if they got to the office safe, if their plane arrived, if they got back from a ski trip safe.  I never cared before.  Why now?  Why?  And now I will spend the rest of my life worrying about them.  Always wondering and always worrying.
