Bait and Switch (Part I)

Nearly a year ago, I told you guys a story about a model who pulled a fast one on me. She agreed to shoot nudity in our texts and then when I arrived to our shoot she reneged on our agreement. (Rules of Engagement and True Intentions http://lucima.podomatic.com/entry/2015-07-29T11_47_11-07_00) So it happened again. Except the outcome was totally different. What changed? How do I feel this time? What is the effective difference between the last time this happened and this time?
