If there are kids involved, you will probably get times to show the "new you" that don't require any extension of invite whatsoever, as in kid's sports events, school events, birthdays, etc. I think one of the most powerful ways to show the 180s is when the WAW finds out from 3rd parties. It's a double win, because it piques their curiosity, and they may wonder why you didn't tell them. Plus, they certainly can't accuse you of fake changes just to impress them!
