My mom would always insist she didn't mind when I drank in front of her and she would even buy me a bottle of wine. Her thing was always beer, so she would insist that it wasn't the same. But then as soon as she got caught drinking again, she would blame me for drinking in front of her! After that, if I did decide to drink, I just wouldn't do it in front of her. My dad never drinks in front of her, but he resents not being able to kick back with a beer after a long day.
I have a friend who has a glass of wine every night in front of her husband and she says it truly does not bother him, for he has accepted that he is an alcoholic and knows that it's not the same for him. My mom can't even see a commercial with alcohol because that sets her off.
