" If you encounter a werewolf in wolf form, you must quickly assess the situation. If he is ignoring you, move away from the area calmly but quickly. If he is watching you, look for the signs of aggression you would look for in a dog - bared teeth, growling, hackles raised. Raise your hands to show you are not a threat (Also try to look as little like roast beef as possible.) "
