When I pick up the cup, don't ask, just fill it. How should I reply?

They say to fill up the wine, so you can go back to the next sentence. Well, we won't get drunk tonight. People say that filling up the wine means drinking more and having fun, but drinking is harmful to your health and makes the person you love sad, so you should give up drinking. After all, it will hurt your health, make people who love you sad and worry about you. Why bother?
