My mom has called me when I’m drunk. Before, when she didn’t know for sure that I drank, I’d just ignore it. Now she knows I drink, and she knows when I’m going out to drink, so I just answer it. Yes, even if I’m really drunk. She usually calls before 10pm (she goes to bed early most nights) and I’m not nearly as drunk at 10pm as I am at 1am. It works out well.
