Look! Seven Deer

Larry dragged me to the back porch and tried to put binoculars in my hand.  He said there were seven deer all lined up. I didn't want the binoculars as I counted five deer.  I told him I only saw five but two might have already passed through the gap.  He put the binoculars back to his face and said there were seven.  I looked where he was looking and counting.  He was counting a different group!
