FI has a huge extended family, many of whom I haven't met. I'm not overly enthusiastic that there will be a bunch of strangers at our wedding --- even FI (and FMIL, to an extent) doesn't know some of the names of distant cousins & their children! We "have" to invite them and are prepared to host everyone if they attend, but I'm really crossing my fingers for declines. On top of that, FMIL is inviting three or four of her friends and their SOs.
My question is, how do you deal with strangers at your wedding? I'm mostly concerned about table visits and the receiving line. Do I just smile and make generic talk? "Hi! Have you tried the chili yet? Thank you so much for joining us!" Or do I introduce myself? I'm sort of freaking out over this.
