They think she’s a drunk, she says she isn’t, the easiest way to find out is ensure she can’t have alcohol. Not that hard to do at a hospital! Seems like a simple idea to me.
Remember, it took several visits to figure this out, and no one even tried this simple thing to suss out if she was truly an alcoholic.
That's my whole point.
Why not make her do hand stands? Why not make make her wear pink?
You are picking a test because you know the disease.
