I've never tried those Craigslist type sites. I'm sure, though, just like in real life there are those "Hannibal Lector" types who try to prey on others. I'm sorry it all happened at once.
I sometimes have to take a break from murder mysteries and other books which portray the negative side of humanity. In fact, I was just asking my fellow book readers here what would be some funny, enjoyable books to read!
