Exwell. When you say that no one in your family will be drinking or want you to drink, this seems inconsistent with your first post on this thread where you said that "everyone" will be drinking. And even if your family is not drinking, they are hardly likely just to stick to themselves but, rather, will probably socialize with the "everybody" you referred to who will be drinking. It seems probable that they will try to persuade you to have "just one", a suggestion which would be heartily welcomed by your AV.
