We've already replied yes, but we know and the B&G know that the invitation and acceptance were given out of a sense of obligation (we are the 'extra' couple in a group; the rest of whom spend a lot of time with each other, but we rarely see).
This is becoming more and more apparent and I'd like to just call it a day, but we've already accepted the invitation. No big deal really but I'm not looking forward to it and no doubt they're not really that bothered if we're there or not. Just seems so fake.
WIBU to decline after all? It's a few weeks away.
