It tends to be a recurring thing that happens, but once we tell someone that we don't care if they announce to the world that we're married, there isn't any more confusion.
Normally it goes down like this: Someone (either a relative or a friend) will be doing introductions and they'll say something like, "This is Mike and his wife Ashley. This is hedgefun. And this is.. (long pause)... [DW's name]." We've even gotten a, "This is my cousin [DW's name], and hedgefun, her, uh, yeah..."
Anyone else run into this or something similar?
