Don't blame the dog on me...

If you think that just because something was an accident, you should not apologize for the harm it caused, one you are a fool and two *Blank Stare*  If you accidentally run over someones dog by no fault of your own, it might still be nice to express regret over the situation considering the person is now down one best friend.  I mean you think stuff like this goes without saying but apparently it does not.  If you hurt someone even when you never intended or imagined doing so, don't be a jerk about it- say sorry!
