So DH, DS and I just came back from visiting DH's family in Egypt. Our closest neighbors (3 households - Bob, Sam & Sue, Jane) were all aware. Neighbor Bob, sent a FB message once we got back saying, "Welcome home, can't wait to hear all about it, come to dinner and I'll invite Sam & Sue and Jane and you can tell us all about it.". Jane isn't on FB so he emailed her with the idea too and she was really excited about it as were Sam & Sue.
The first weekend in January didn't work for us, so the next weekend (Jan 12th) was suggested. I said we were available over FB. I was speaking to Jane later and she told me she couldn't make that date. I passed that info along to Bob and Sam & Sue via FB. Next FB message is from Sue saying "Ok, we're good for the 12th, is it on?". I reiterated that Jane was unavailable, but it was up to Bob. Bob then acknowledges it's on for the 12th and gives times.
I feel like Jane has been forgotten and while it's not my party, I feel rather awkward since she is the neighbor I have the most communication with out of the bunch. I've already mentioned twice that she is not available on that date, but I feel badly that maybe she's been left out. Should I say anything?
