[The_Rorschach]

Moral obligation? Moral obligation?

I never really considered drinking to be a moral matter. Furthermore, if she is restrained in her drinking, I see no reason to interfere. If she is not, then you have justifiable cause granted through her own actions. Certainly you have no right to capriciously dictate the terms anyone other than yourself must live by, only a mad ego could convince you otherwise.

My sentiments fall into line with Ziggy's on this one.
