Unusual Behavior

Bob M seems to be sticking up and defending me a lot lately. I find it a little unnerving. For instance, today in class, he was defending several of my answers to the process model for me. Plus, he's been very friendly lately. Has he decided to befriend me? I still have hard feelings toward him, and probably always will, for trying to fire me. I'm curious to see how this will play out. If it's one thing I've learned in my time there at work, nobody does anything without an ulterior motive.
