I've got a friend who I know is a furry. I've explained to him what furriness is, what we are like, and what we do. He has shown his furriness to me many times, but he still denies it! He won't admit he's a furry! He's sent me furry stuff, and he's referred to himself as "Squirell" and "Brushtail" (his spirit totem is the squirell), but he won't come out and accept it! What (and should) I do?
