Yes, beginning to wonder. She has invited herself to events at my house in the past. I posted about dinner for Canada Day, she asked what time? She wasn't joking . Luckily, she did not show up with him that time.
What bugs me is we have had her over so many times and she has never reciprocated... not even to ask out to a restaurant or happy hour.
I am beginning to see how one-sided this is and that our manners are quite different.
