In all, the person I am frustrated at the most is myself. I did the right thing. Looking back I now, I wish I had been brave enough to do more, to do what needed to be done. Of course, the person that is actually at fault in this situation blames me. No good deed goes unpunished, right?
It's one of those situations where you realize that some people are just stupid. When actions have no other rational excuse other than stupidity, that must be the reason. Mix Ocam's Razor with Quacks Like a Duck theory and you end up with one answer. STUPID.
Understanding that STUPID is the reason for this person's behavior does make me feel better. I have to revise my expectations of this person. The, "I'm sorry you are upset" was translated as an apology for my actions. Why? Stupid. Action needed? For me not to care. I will decrease the importance/prioritization of this problem down to well below getting the dog to the dentist. It just doesn't matter because you can't fix stupid.
This realization has been cathartic for me. I'm not quite at Master Shi-Fu's level of inner peace, but I'm on my way.
How's your holiday going so far?
