Thanks, CV. Yes, I'm going to have to try to find a different housemate. It's always a crap shoot. I've had better and I've had worse.
I'm sorry I couldn't find that secret formula. I feel like I did my piece sufficiently in this context. I did enough work on me to get past my anger and get to a place where I could be kind and respectful. I didn't completely get over thinking about what P thought, but since she wasn't giving me grief I thought I should seize the moment. I'm sure I'll have plenty of other opportunities to work through my angst about P's thoughts.
