Soshi was by all means not antisocial he just had a very specific view on life.  It was his way or the highway so to speak.  He would bring up the rear of the group silently.  As he peered out from under the wide brim straw hat of his.  He would take in all of the others from the group from the dragon, the crab, to the crane, and finally his own family courtier along with them.  He would move his horse along the ever present scowl sat on his face.
