I am sorry, One With Wings, I meant no harm by my comment. Just speaking from personal experience. I can't walk past someone who smells of gin and cigarettes without thinking "Grandma"!
You have every right to your boundary. Your house, your rules, your sobriety that you are protecting with everything you have. She may pout for a while, but she will get over it and learn to work with your new boundary.
Best to you and all your family for this coming holiday!
Hugs, HG
