Magic Forums

So I was going through some of my old forum posts and I found an inquiry of mine about Faelatry. The Faelatrist who responded to my inquiries mentioned something about how you shouldn't thank the fae or talk about why you can't. But other sources say that you should always thank the fae when they do things for you or visit with you. So I'm confused. Should you thank them or not? Is there a reason why you can't talk about why you shouldn't thank them if you shouldn't? Does it all just depend on the particular fae your visiting with? I don't think I've visited with any fae, I'm just really curious.
