That's your opinion, in my opinion is a fun scene and Anne is acting like several other thousands people could do. Anyway, relax, is just a game you can always use the skip scene, so Anne doesn't drink!
But there are so many other scenes with it, I've found they really can't be avoided... The download at least needs a warning about all the alcoholic content. I don't remember seeing anything about it on its page.
That actually makes it sound a little bit like an eroge. xD Um, how about "includes sexual themes but nothing explicit, as well as alcohol usage." Because while there are sexual themes, it's nothing too explicit. No worse than on a sitcom really. lol
Edit: Where for Nicole, it has "light sexual themes". This Roommates was a lot heavier on them.
