So Brandon called me and was wondering what the difference was between fur and hair. I thought about this a lot, without a dictionary, because I’m sure that would be cheating. And I think it’s pretty simple. Fur is a collection of hair. But often it is considered rude to call someone furry. So hair is really just a polite term. A point of etiquette if you will. And of course there are the parts of human society that would prefer you call them furry. So really if you are a guest in an unfamiliar animal phylum you should politely ask your host the preferred term.
