Oh, we don't cut them off! They are people who, for their own reasons, would rather live in muggle society than ours. Strictly speaking, if they use magic for fortune-telling then they are breaking our secrecy laws, but if they are doing no harm then the authorities tend to turn a blind eye.
Mr Samara, I must apologise. It was quite inappropriate for me to tell you of my troubles that way, wasn't it? I can assure you that it isn't something I make a habit of.

I think it an interesting creature to have chosen you. There are stories in my culture about very powerful wizards who can communicate with snakes.
