Alpaca are kinda like a cross between a sheep, a kitten, and a giraffe. By which I mean they’re furry, friendly, and they have long necks.
Llamas, on the other hand, are apparently like a cross between a sheep, a camel, and Viking berserker. By which I mean they’re furry, they hate you, and they will fucking destroy all things that oppose them.
As it stands, Pat Rothfuss is almost certainly kissing a llama.
