I've been out for surgery for a few things, Gallbladder, Tonsils, and each time I tell the truth it gets all twisted so now when people ask why are you going to be out for awhile (This time for vacation) I just tell them, Well according to the Rumor Mill I'll be having an Alien Baby. They laugh and move on.
I prefer to embrace the Rumor Mill idea it makes my life seem interesting. Sad I know but fun.
