Leader of the alpaca

I don't know how good it is at spelling and grammar, but the alpaca is in many other ways a remarkable animal. It spits when it is angry and hums when it is happy. When I say "hums", I don't mean the slang use of hum, which began its life as an onomatopoeia for the sound bees make and later became a synaesthetic word describing the fragrance of an unwashed body that smells so strong as to be almost audible.
