At the beginning of this story, I totally agreed with Gertie that Knox was being pushed around by his girlfriend and he was letting her. By the end I saw Knox's point of view as well. I'm just glad they both synced up and finally seen what the other was feeling.
Hated Knox's girlfriend but she turned out not to be his girlfriend anymore so it's all good. She was a typical pretty bitchy character, she changed Knox from the beginning and that's what distanced him and Gertie.
Sex between 2 long-time friends could be awkward but Knox and Gertie's managed to be tasty. I think the whole knowing someone that well can most definitely help when it comes to seducing them .... it certainly worked for these two.

balanced anthology. each author had different styles of telling stories, and found resolution in their indiividueal storeis. Nice atmosphere and locations.
