Negativity

I try to be a positive person.  I think most people do but there is always a few negative people that can ruin a positive person's day.  My last couple of weeks has been wonderful.  Things were falling into place.  Things that were difficult at first now seemed so easy.  Most importantly, I was spending time with someone very special to me.  Overall, a very positive situation.  Then came the negativity.  I was having dinner in a local restaurant and everything was going well.  Then I heard an intercom announcement that there was an issue with my car.  I thought maybe I had parked in the wrong spot.  The news was that someone had hit my car.  I walked outside to see my front bumper hanging to the ground.  I had to take a few deep breaths to remain calm.  Whoever hit my car did not stick around.  It was a hit and run.  I don't know why the person just left.  I can only speculate.  It was this negative act that almost ruined my night.  This is the type of moment when you have to decide if you will go down a negative path or if you will remain positive.  I remained positive.  What would you have done?
