Sometimes a conversation that you've had literally hundreds of times before can still yield some unexpected twists.
Case in point - I was having that same old 'Would you rather be a Vampire or a werewolf' conversation the other day*
*Werewolf. The correct answer is always werewolf.
The person I was speaking to came down on the side of vampire, but acknowledged that there might be a logistical hitch as she is a vegan.
This led to an hours long debate as to whether or not consuming human blood counted as a no-no according to strict veganism.
In the end, research seemed to indicate that it all depended on whether or not you consider a human being an animal. If yes, then no-go for Vegan Vampire, which feels like a win for the anti-evolution crowd somehow, but I can't exactly put my finger on how.
