It is always fun confusing your mother in law….
My mother in law, who is totally against drinking alcohol and certainly absolutely against me inducing my father in law to drink is almost always a picture of confusion every time we have dinner together. I ordered a mocktail (non alcoholic) for her and when the drink came, I casually mentioned that she might like the alcohol in that drink and that I was quite sure she had not tried it before. You can see her protestations and refusal to drink.
Then my brother – who had stepped out to take a call – came in and made a short shrift of my lie. You can see my mother in law’s reaction in the next picture. In fact, we had to get a second one!!
