During my sitch, I caught my wife taking my personal prescription info out of my drawer (for my ADs), and stashing it -- presumably to use against me legally (I later confirmed that was the case, thru intel). So upon advice on got on this forum, I printed out a whole bunch o' stuff from the internet about the HPAA laws, and how that's a felony, and purposely left it lying on the kitchen counter.
I also RETURNED the paperwork that she had (it was the label and that printed out list of side effects, etc., that typically accompanies a prescription) to its rightful owner.
Of course, the really cool dynamic of this whole thing -- which was NOT lost on me at the time -- was that there wasn't a damned thing she could say about me taking it from her drawer, because she wasn't supposed to have it to begin with!!
The other really foolish thing she did (my DB mentor had this theory that people in affairs instantly lose 40 I.Q. points. He was dead serious, and I think pretty accurate in that assessment, actually) was that -- even AFTER I "stole" the prescription paperwork back from her drawer and returned it to MY drawer the FIRST time, she did it AGAIN a second time, and then when I took it back AGAIN (this was before I printed out and left the HPAA stuff for her to find), she made note of what my two prescriptions were on a piece of paper, so she wouldn't have to take my paperwork again. So now I had her notes, in her own handwriting!!!
