One time, my Aussie boss invited me to his birthday party. When I arrived, he asked, “Aren’t you going to drink?” I was confused. Then I noticed that everyone he invited had brought their own drinks. Not to share, but for their own consumption. It turns out that in Australia, when someone invites you to a party, you’re expected to bring your own drinks. This was surprising to me because in the Philippines, when you’re invited to a party, you usually just bring yourself.
