HD, I don't know if my last "pit" thing with BB is helpful or related but here goes.
Last nite, I asked BB "Arbys or Pizza Hut" She said Arbys was fine. We don't have a budget for anything but to pass my requirements, I look for deals/specials.
I told BB what Arbys had on special but she did not take my word, so I showed her. I said this is the last time I was going to give proof about what I was talking about. I said if she can't trust my judgement and observations, that I was a trustworthy person in her eyes and no matter what I might do in the future, she would have some doubt. I said trust me to do the right thing or something close or don't trust me. There is not much I can say to change her mind or prove myself trust worthy other than just trusting me and see how it turns out, then evaluate the results.
So, If I can remember, and I think I can, I am not going to try to prove to BB what I say is true. It is OK if I am not 100% right. I will try to be accurate most of the time but will make mistakes and that is OK. BB is going to have to accept that on common everyday things. Federal cases are another story.
I found the harder I try to please someone that is being picky or unreasonable, the more crap they can come up with till the game is no longer worth playing.
Somehow the OP has to know this too. Maybe things will change, maybe they won't. I am not going down with them is my feelings right now.
I didn't want to be responsible for anything that might go wrong with the camera, so I felt better just drawing a bright line between me and it. Most things start out as "our" but if there is a long term problem, then "Our" becomes either hers or mine or there are two of them, like the OJ thing. Things like cell phones are mostly hers or mine even though I pay and provide some technical support
