@mangeurdenuage maybe she just tried to be polite but careful. i'd certainly be as woman and not just go to some invitation at someones house. never know what happened to her in the past.
i agree that these things are sometimes dreadfully complicated though.
@mangeurdenuage
i didn't take that you were criticizing her :) things are absurdly complicated because people seldom really speak their mind, which often makes things totally complicated.
i somehow understood that you were inviting her over to the meal with your sister - guess it's another proof of "communication is complicated" :D
