Thank you for your advice. My dad took all alcohol out of the house. I dont drink so she doesnt need to worry when being around me. The thing is though...they always had a glass of red wine for dinner and she wouldnt even finish it....or a beer at a cook out. But my dad said she is literally a closet drinker. She hides bottles and only drinks alone or behind his back. He can obviously tell shes drunk but never actually catches her drinking. He said he even put a bottle on the table and said go ahead drink but she didnt. When they go out with friends or on vacation she still doesnt. Its just when shes home. Why? I want to understand what makes someone be a closet drinker as opposed to my mom who is a social drinker ( also drinks at home but doesnt hide it).
