Might I just add that I can potentially see why this situation could be troublesome, depending on what type of medication it was. (NOT that I want to know, nor am I trying to suggest anything about your husband's medical state.)
Thankfully, I have not had to deal with what you guys are going through, but I can only imagine what an ordeal it could be. I am, however, female and I know how spiteful and vindictive we gals can be.
ESPECIALLY when our children are involved. So I can easily see how, depending on the contents, she could see this as information that she could use against him, so I can understand your angst.
I don't think that anyone was trying to make light of the situation or make fun of your question. Honestly, we joke around a lot here and I have to admit some of the comments made me giggle too. I don't think anyone meant to offend you and I'm sure no one expected you to take it so seriously. I don't think anyone realized the seriousness you were placing on the incident.
