Was it assumed you'd assume you were going as your opposite number was invited, as was all the staff. Heck I would!
I wouldn't even sweat about it - just when you're discussing it in open conversation, talk as if you're going and wait till you're told otherwise. THEN you can make a fuss about being left out. Until then, assume the best.
I was in this situation with clients a few years back. They hold an annual lunch and until I got hold of it they never knew the exact numbers until the day itself (these are restaurateurs!!!). Now we know well in advance, the hotel restaurant (one of the members) has the numbers on the Wednesday prior and I name badge all the guests. He he he.
Anyway, the first year I was invited last minute. The next year I was invited during the meeting when they discussed it. The following year, the chairman had changed and she was discussing everything with me one day so I just said to her, and I assume I'm invited? She was horrified that I had to ask and said I should just assume this was the case (they host the whole thing and it's a freebie I enjoy!) For the last 4 years therefore, I've not asked if I'm invited, I've just assumed. After all, I do all the blinking hard work organising it - the date is set practically a year in advance, I liaise with the hotel re numbers and seating (but I get to deal with the hotel's GM as he is also another of those assumed invitees, and so as we know each other well, it's a doddle!). I get the thank you cards and emails (which I also pass on!) and everybody is quite good at returning their badges to me - I think I once already posted elsewhere that I recycle them for the next year as our guests don't vary too much!
Anyway, that was a long way of showing you how easy it is for folk to assume that you know you're invited, when you're not sure. I say brazen it out and assume you're invited and go. After all, if you turn up on the day and it turns out you shouldn't be there, nobody's going to make a fuss and kick you out, are they?
Enjoy!
