I was walking a dog on a beautiful day.  It is not uncommon for passers by to say hello to whatever dog I have with me.  There was a couple across the street headed to their car.  They were young (mid-late 20's?)  She was skipping actually...  and she looked at Peyton and said, "Hi dog!"  Peyton stops dead in her tracks and perks up giving this girl her full attention.  They weren't coming over, so I said, "Apparently she responds to Hi Dog!...  "  Then the girl laughed and said, "Ha, so do I!"
