Spooky or Creepy?

Here's one of the reasons I enjoy living in a multi-ethnic community.

At table the other night, one of my brothers for whom English is not his first language asked, "What's the difference between creepy and spooky?"

This sparked the kind of discussion I just love. Yes, they are similar, but there is a difference. Where does that difference come from? Some things are spooky, but not creepy. Some things are creepy, but not spooky. And some things are both creepy and spooky!

I don't know how far we got in answering his question, but it was a great conversation!!
