Ah the Story of a puppy...   A nervous puppy who has brave days, and not so brave days.  He seems to be growing by the hour.  We rounded a corner and ran into a lady, literally.  She was startled, Sammy was startled, and it resulted in a very trepidatious walk around the neighborhood that ended with me just picking him up and hugging him because he seemed to need it.  Although he is still a puppy, he has grown quite a bit since I first met him.
