On the one hand, the Elders™ are sneaky bastards for going through your sister to get to you.
On the other hand, now you can invite your friends and family to join you on Monday or Tuesday for a nice restaurant dinner and let them know that you love them and want nothing but happiness for them and for you, and that you will always be there for them. You can beat the elders to the punch by taking advantage of as much Association™ as possible before they make the announcement on Wednesday night. You have an opportunity that a lot of people don't have, because in many cases the Elders™ don't bother to inform people of their decision to make an announcement. They didn't tell us that they were going to announce that Mr Scully had "written a letter" and DAd himself (complete fabrication) - we found out almost a year after the fact.
I think a kind of "send off dinner" would be an awesome way to kick off your newfound freedom.
It would also give you an opportunity to leave the door open to people who might wish to seek you out if they begin to have their own doubts.
