Hey guys, working on finalizing the guest list. We have a couple of family friends that I would definitely like to invite the parents of, they are close friends of my parents and I've known them forever. I also grew up with their children (to varying amounts) and in each family there is one child that either I or my sister were particularly close to. I would like to invite just the parents and the one adult child of each family but am worried this is rude to exclude the other kids? Unfortunately, since they are all grown if I invite them all that would be an additional 12 or more people (including their SOs/guests). That's just too many! My sister and mother have reassured me they will all understand (and I think they will...) but now that's it's coming down to it I'm just not sure...
