Hi, I'm visiting Australia for the weekend. I'm not so enthusiastic about the drinking but the rational conversation sounds great. Is it ok if I drop by?
Hi mira, we would absolutely love to have you! Most of the Melbourne Social events are sober affairs, and the drinking will be only a minor part of the evening for some of the participants. Come early if you want to get to know people while it is quieter.
