Are you just going to sit there?

During a safari in the wilds of Africa, this group came upon a herd of wild elephants.  They came to a stop and sat very still waiting for the herd to pass.  When one of the big bulls took notice of the group and came over to check them out.  The tracker/guide sat motionless as the elephant checked him and the group over before he meandered on.  Do you think the sound of someone soiling them selves would spook them?
