Notice, she offers flattery, not praise. There is a big difference between flattery and praise. Flattery has an evil motivation behind it.

Wormwood was a drug that grew in the wild. Initially, when you chewed on it, it would taste sweet like honey, and it would make you feel great. But as the drug wore off, it would actually bring on headaches, depression, and could eventually destroy the mind. Just like the drug wormwood, the prostitute will give you a short time of sexual pleasure, but after the excitement comes a terrible bite. In the end, if you do not turn from her, the strange woman will use you until your very body and soul are destroyed.
