DH and I are friends with a couple who live locally. We’ve known them a few years, we don’t meet that often but we tend to take it in turns to have them over for dinner and we go to them. We’ve always enjoyed their company and likewise they’ve always commented they enjoy seeing us.
The last couple of times we’ve hung out we went over to their house both occasions and their DD was there and joined us (for the whole evening not just the meal part)
For context, their DD is in her forties and has her own place but often visits her parents on the weekends. The second time we went and the DD was there again I was secretly a bit disappointed, they hadn’t mentioned it beforehand and we were looking forward to spending some time with just them, also we don’t really know their DD and we were polite but the conversation felt a bit awkward and self conscious. Obviously we didn’t make a thing of it as it’s their home and their choice so we thought fair enough.
Recently we invited them over for a meal as as we haven’t seen them in a while, partly because we’re overdue hosting them but also I’ve had a lot going on and thought it would be nice to catch up just the two of them. We also invited another mutual friend they haven’t seen in a while who they wanted to catch up with too so would have been five of us at the meal.
Anyway the wife of couple has texted (meal is later this week) and said their DD will be with them and has asked if she can join us for the meal at ours. The text was polite but direct and not really phrased as an option to decline (eg didn’t say ‘no problem if not convenient for DD to come along’)
We feel awkward and put on the spot as don’t dislike their DD but having an unplanned sixth person feels it would change the dynamic, equally worry if we say no we will offend them. They speak very highly of their DD and are obviously very close as a family.
If we had a pre existing connection with the DD or if she was a child/teenager and no childcare options then that’s different, but she’s not and it was clear she wasn’t part of the invitation when we asked them over. We aren’t hugely sociable people and both DH and me aren’t keen on the request but I feel if we were more sociable we’d probably be ok with it - more the merrier type thing. Also we don’t have children so wondering AIBU to find this a bit cheeky and feel miffed?
