IME, Mummy...us kids of alcoholics know- even when we don't know the term- that our parent(s) drinking isn't "normal." My mom being honest with us was something I craved, and it took her a long time - even into my recovery- to be as honest as she could. And I realized that, well, 99% of the people around me, even casually, knew I had a big problem.
It's one we can face and one we can turn our lives around from entirely.
