Me, dd and dp have been invited to his mum's for christmas and she's requested that everyone brings a dish because it will all be too much for her. There's going to be 8 of us altogether. Dp informed me that we're doing the roast potatoes and when I asked him why he said because his mum can't do it all. Last year we hosted for 6 and cooked the lot with no problem and the guests brought snacks and drinks with them which I thought was standard. Anyway his mum came last night and dp told her he'd bought a cheesecake for xmas pudding and she snapped back asking why we aren't making one. AIBU in being a bit irritated by it all?!
