When a mother-in-law has faith in you

Tonight, I called my mother-in-law and requested her μουσακά (mousaka) recipe. I told her a friend in America wanted it, and she started laughing hysterically. She said "and I thought you might be making μουσακά", as if there is no way in Hades I'd ever be making μουσακά. I sheepishly told her that I might make it someday, although she is probably right. Still, did she have to rub it in?
