I understand zombies being completely out of their mind when fresh flesh is around, but is there ever a kinder gentler side to a zombie? For instance, this zombie seems still very concerned about dental hygiene. Possibly others, once they have temporarily quieted their hunger are more contemplative. You never see zombies attacking other zombies. Possibly as they all lurch their way towards their next set of victims if another zombie bumped another zombie they would actually say "Oh I'm sorry I didn't see you there." and the other zombie would reply back "It's ok. We're all in this together." Then they would smile and continue on.
Stop Human on Human violent crimes I guess is what I'm trying to say. Be more like a zombie.
