Dru didn't necessarily not want them to think she was a witch, though. When I was eight or nine, my friend and I told some neighborhood kids that we were real witches, and we'd pick random leaves off plants and do pretend spells, just because we liked the attention and we liked feeling special.

I thought it was good story. I thought it was weird Dru dressed like this, but I thought it was interesting. I liked how Dru said she wasn't a witch but her grandmother might be. When I was younger I thought that was cool.
I wonder if Dru was aware, or more to the point if Mrs. Porter was aware, of how convinced Karen was of her being a witch. I can imagine that Mrs. Porter might have deliberately played it up to play with Karen!
